Activity 8-1: Statistics Vocabulary Part 1
Name:

Mean – The mean of a set of numbers is the same as the average. To determine the mean, add up all of
the numbers and divide by the quantity of numbers.
MEAN =
7 + 7 + 17 + 17 + 25
= 14.6
5
The mean is 14.6.
Median – The median of a set of numbers is the middle number when the numbers are lined up from
greatest to least. In other words, half of the numbers are more than the median and half of the numbers
are less than the median.
7
7
17
17
25
17 is the median of this set of numbers.
If two numbers are in the middle, the median is determined by averaging those two numbers.
Mode – The mode of a set of numbers is the most common number in a set. If two or more numbers are
the most common, all of those numbers are the modes. If all numbers in a set are in equal amounts,
then there is “no mode”.
The mode of the set of numbers above is 7 and 17.
Range – The range of a set of numbers is the difference between the smallest and largest numbers.
The range for the set of numbers above is 18 (25 − 7) .

Activity 8-2: Statistics Vocabulary Part 2
Name:
Variation is the spread of the data. If there is a lot of variation it means the numbers are spread out all
over the place. If there is little variation it means the numbers are all pretty similar. Range is one way
we have already learned to measure the variation.
With large sets of data it is often helpful to separate the data into four equal parts called quartiles. The
quartiles are used to find another measure of variation called the interquartile range. This is the range
of the middle half of the set of data.
Students in math class are divided into 4 groups with one-fourth getting the grade of a D, one-fourth C,
one-fourth B, and the best one-fourth get an A.
DDDDDDDDCCCCCCCCBBBBBBBBAAAAAAAA
This is the
median. It breaks
the group in half.
This is the lower quartile.
It breaks the bottom half in
half.
This is the upper quartile.
It breaks the top half in
half.
Lower Quartile – The median of the lower half of the data.
Upper Quartile – The median of the upper half of the data.
Interquartile Range – The difference between the upper quartile and the lower quartile.
Examples:
Lower half of data

Activity 8-3: Skew & MAD
Name:
Symmetric – A symmetric graph typically has a high point or peak in the middle of the data set. The
mean and median are or about equal. The mean is the best measure of center.
Skewed right – A right-skewed graph has much of its data to the left with only a few data values on the
right. The mean of the data set is greater than the median. The median is the best measure of center.
Skewed left – A left-skewed graph has much of its data to the right with only a few data values on the
left. The mean of the data set is less than the median. The median is the best measure of center.
Our principal asks every math teacher to estimate the amount of time our students spend studying each
week. Mr. Mangham decides to estimate the amount of time by taking a sample of 8 students in his
math class. Then, he can determine the mean amount of time students spend studying each week.
In the situation the population the entire group of students that Mr. Mangham could collect data from.
The sample will be the 8 students that Mr. Mangham random chooses to get data from. You would say
that the sample size is 8.
Mr. Mangham gets the following data: 60, 120, 50, 150, 150, 50, 100, and 200.
The distribution of the data is called its variability. The variability of data describes how spread out the
data is. This can also be described as the spread of data. One measure of variability or spread is the
range. Another measure is called the mean absolute deviation. The mean absolute deviation is the
average of the absolute values of the deviations of each data value from the mean.

Activity 8-3: Data Displays
Name:
Bar Graph
• A display in which numbers are represented by bars whose heights or lengths correspond to the
magnitude of the numbers being represented.
• Compares data from several situations.
Line Graph
• A line drawn through pairs of associated numbers on a coordinate grid.
• Time is graphed on the horizontal axis.
• Used to show changes over time.
Circle Graph
• A display in which parts of a whole are represented by sectors that show the fraction of the
whole taken up by each part.
• Often called a pie chart.
• Allows you to visually compare a part of the data to the whole set of data.
Line Plot
• A display of data that uses stacked Xs to show how many times each data value occurs.
• The values are listed on a horizontal number line.
Stem-and-Leaf Plot
• Displays a collection of numbers in which the digits in certain place values are designated as the
stems and the digits in lower place values are designated as the leaves.
• Leaves are placed side-by-side next to the stems.
Venn Diagram
• A visual aid that uses circles to represent sets and the relationships between them.

Activity 8-4: Box-and-Whisker Plots & Scatter Plots
Name:
A box-and-whisker plot summarizes the data using the median, the upper and lower quartiles, and the
highest and lowest, or extreme values.
Directions to construct a box-and-whisker plot:
1. Draw a number line at least as long as the range of the data.
2. Place vertical lines above the number line to represent the lowest value, lower quartile, median,
upper quartile, and highest value. The lowest and highest values are called the extremes.
3. Draw a box containing the quartile values. Draw a vertical line through the median. Extend the
whiskers from each quartile to the extreme values.
Example:

Note that all the numbers on the line are evenly spaced.
This is very important for a box-and-whisker plot.
When you graph two sets of data as ordered pairs, you form a scatter plot.
If the points trend upward to the right, there is a positive relationship.
If the points trend downward to the right, there is a negative relationship.
If no trend is evident, there is no relationship.
Positive relationship
For example, the more
passes you throw the
more yards you will get.
Negative relationship
For example, the more
points you score the
fewer games you will
lose.
No relationship
For example, the amount
of times you win the coin
flip does not affect how
many games you win.

Activity 8-5: Titanic Team Project
Name:
“How could we have saved more people aboard the Titanic?”
Create an exciting, entertaining, and informative Titanic Survival display
Assumptions:
You left for New York at the same time with all the same passengers and equipment aboard.
You will still encounter the iceberg along the way.
Main question to answer:
•
•
How could we have saved an additional ________ people?
You goal is to prove your answer to this question MATHEMATICALLY.
Display Requirements
Each group will be given one piece of posterboard. Your display must be on one side only.
•
•
Use the mean, median, mode, and range of a set of data (at least 8 numbers) to make a
conclusion
Find the quartiles of the same set of data to make a conclusion
Create a box-and-whisker plot of the same set of data to educate the reader
•
•
Create at least one graph to display important data to your reader (graph paper)
Create a table of the data used in your graphs (optional)
•
As part of your description on how to save more people show at least one unit conversions in
each category below:
o Customary units
2. Metric units
3. Rates (ex. ft/sec to mi/min)
•
Demonstrate your knowledge of rates, unit rates, and ratios in some fashion to help the reader
understand a topic.
•
Hints of advice for getting a maximum grade:
Creative approaches to solving the problem are welcome. Make sure to use real data about the
Titanic to support your approach.
The more you demonstrate your math knowledge, the better.
Neatness matters, however your grade is not based on the most colorful. It is mostly based on
the math.
You are responsible for completing the math, not a computer or calculator. Do not show
calculations on your display - use a separate sheet of paper.
Feel free to add any “extras” to make your display more appealing. Cite any sources you use.

Activity 8-6C: Mean Absolute Deviation
Name:
MAD (mean absolute deviation) is another measure of variability (like range) in a data set. The mean
absolute deviation (MAD) is the average of the absolute values of the differences between each data
value in a data set and the set's mean. In other words, it is the average distance that each value is away
from the mean.
If a data set has a small mean absolute deviation, then this means that the data values are relatively close
to the mean. If the mean absolute deviation is large, then the values are spread out and far from the
mean.
To find the MAD:
1. Find the mean
2. Subtract each data value from the mean
3. Take the absolute value of each value from step #2.
4. Add up all values from step #3.
5. Divide by the number of data values.

Activity 8-11B: Scatter Plots
Name:
When data points are not completely linear, a trend line is used to allow us to make predictions from the
data. A trend line indicates the general course of data.
A scatterplot is a graph that displays bivariate data on a coordinate plane and may be used to show a
relationship between two variables.
Bivariate data shows the relationship between two variables. Example: Ice cream sales versus the
temperature on that day. The two variables are Ice Cream Sales and Temperature.

Activity 8-11E: Scatter Plots
Name:
Two variables are related in a positive association when values for one variable tend to increase as
values for the other variable also increase.
Two variables are related in a negative association when values for one variable tend to decrease as
values for the other variable increase.
When a linear pattern, such as one of the form y = mx + b , describes the essential nature of the
relationship between two variables, they have a linear association.
When a non-linear pattern, such as a curve, describes the essential nature of the relationship between
two variables, they have a non-linear association.

Activity 8-14: Measurement Conversions
Name:
There are several different ways to convert between units of measurement. One way to convert metric
units is to memorize the sentence:
King(Kilo) Henry(Hecto) Died(Deka) [base units, gram, liter, meter] Drinking(deci) Chocolate(centi)
Milk(milli)
Another way is to use proportions:
Example
14 gallons = x qt.
Use the fact that 1 gal = 4 qt.
Example #2
14 qt. = x gal.
1 gallon x gallons
=
4 quart 14 quarts
1 • 14 4 x
=
4
4
3.5 gal = x
1 gallon 14 gallons
=
4 quart
x quarts
1 • q = 4 • 14
q = 56 quarts
In accelerated math we are going to also introduce dimensional analysis. This method will better
prepare you for advanced math and science classes in the future.
Example
14 gallons = x qt.
14 gallons 4 quarts
•
= 56 quarts
1
1 gallon
Let’s say you want to convert 55 miles per hour to feet per second.
Example #2
55 miles 5280 feet 1 hour 1 min. 80.7 ft.
•
•
•
≈
1 hour
1 mile
60 min. 60 sec. 1 sec.
The units cancel each other out leaving just feet per second left. This tells you that your answer is in the
correct units.

Activity 8-18: Metric System
Name:
The metric system is a decimal system of physical units based on its unit of length, the meter.
Introduced and adopted by law in France in the 1790s, the metric system was subsequently adopted as
the common system of weights and measures by a majority of countries, and by all countries as the
system used in scientific work.
The meter (m), which is approximately 39.37 in., was originally defined as one ten-millionth of the
distance from the equator to the North Pole on a line running through Paris. Between 1792 and 1799,
French scientists measured part of this distance. Treating the earth as a perfect sphere, they then
estimated the total distance and divided it into ten-millionths.. The measurements of modern science
required greater precision, however, and in 1983 the meter was defined as the length of the path traveled
by light in a vacuum during a time interval of 1/299,792,458 of a second .
All metric units were originally derived from the meter, but by 1900 the metric system began to be
based on the mks (meter-kilogram-second) system, by which the unit of mass, the gram, was redefined
as the kilogram, and the unit of time, the second, was added. Because of the need of science for small
units, the cgs (centimeter-gram-second) system also came into use. The unit of volume, the liter, was
originally defined as 1 cubic decimeter (cdm3), but in 1901 it was redefined as the volume occupied by a
kilogram of water at 4° C at 760 mm of mercury; in 1964 the original definition (cdm3) was restored.
A series of Greek decimal prefixes is used to express multiples; a similar series of Latin decimal
prefixes is used to express fractions. These prefixes have been adopted by and expanded in the
International System of Units.
The U.S., Great Britain, and other English-speaking countries use inches, feet, miles, pounds, tons, and
gallons as units of length, weight, and volume for common measurements. Today, however, within the
framework of the International System of Units, these English-system units are legally based on metric
standards.
In the U.S. several attempts were made to bring the metric system into general use. In 1821 Secretary of
State John Quincy Adams, in a report to Congress, advocated the adoption of the metric system. In 1866
Congress legalized the use of the metric system, and from that time this system was increasingly
adopted, notably in medicine and science, as well as in certain sports, such as track. In 1893 the National
Bureau of Standards of the U.S. adopted the metric system in legally defining the yard and the pound.
In 1965 Great Britain became the first of the English-speaking countries to begin an organized effort to
abandon the older units of measurement. Canada, Australia, New Zealand, and South Africa quickly
followed and soon exceeded the speed of change in Great Britain. In 1971, after an extensive study, the
U.S. secretary of commerce recommended that the U.S. convert to metric units under a ten-year
voluntary plan. On Dec. 23,1975, President Gerald R. Ford signed the Metric Conversion Act of 1975. It
defines the metric system as being the International System of Units as interpreted in the U.S. by the
secretary of commerce. The act coordinates the metric effort, but does not specify a conversion
schedule.

Activity 8-26: Problem Solving
Name:
1. There are 12 coins that are numbered 1 through 12. Eleven weigh the same and one is either lighter
or heavier than the others. Using just three weighings with a balance scale, devise a scheme that will
find the counterfeit coin AND determine whether it is lighter or heavier.
2. A prison guard and his bloodhound are chasing an escaped prisoner. The prisoner has a 10 mile head
start but the guard is walking 1 mph faster than the prisoner. The bloodhound is trained to run to the
prisoner, run back to the guard, and then continue running back and forth between them. If the
bloodhound runs 10 mph, how far does the bloodhound run before the guard finally catches up to the
prisoner?
3. If one has already driven one mile at 30 mph, how fast must one drive the second mile so that the
average speed for the trip equals 60 mph? (Hint: The answer is not 90 mph.)
Suppose you want to invent a metric clock using the system below.
1 day = 10 metric hours, 1 metric hour = 10 metric minutes
1 metric minutes = 10 metric seconds, 1 metric second = 10 metric miniseconds
If you start a standard clock and a metric clock together (midnight or metric 0), what is the time in our
standard system when the metric clock registers 4 metric hours, 5 metric minutes, 6 metric seconds, and
7 metric miniseconds.
Suppose a metric calendar uses the system below.
1 day = 1 metric day, 1 metric week = 10 metric days
1 metric month = 10 metric weeks, 1 metric year = 10 metric months
If both calendars begin at 0 B.C., what was the metric calendar date on January 1, 2005?

Activity 8-27: Who Finished When?
Name:
(Taken from Algebraic Thinking: Grades 6-8, Lawrence & Hennessy)
Allie’s walking rate is 2.5 meters per second. Her younger brother, Matt, walks 1.5 meters per second.
Because Allie’s rate is faster the Matt’s, Matt gets to start the race at the 25-meter mark. If race is 100
meters long, what happens in the race?
There are numerous ways to solve this problem (rates, tables, graphs, proportions, pictures, and more).
Explain your strategy for solving this problem and give evidence to support your answer. Show your
solution step by step with an explanation of how you arrived at your answer. Do all this work on a
separate sheet of paper and then answer the following questions.
1.
Who wins the race?
2.
What was the winning person’s time?
3.
By how many seconds did the winning person win?
4.
By how many meters did the winning person win?
5.
If Allie won the race, at what point in time and at what distance
did she catch up to Matt?
6.
What if there was no head start? By how many meters and by
how seconds would Allie have won?
7.
Where would Matt need to start to make the race end in as close
to a tie as possible?

8. Create a line graph of the original race. Place meters on the y-axis and seconds on the x-axis. Draw
a line representing Allie’s race and another line representing Matt’s race. Use graph paper.
9. Create your own race amongst five runners. State each runner’s speed and the amount of head start
he or she should get if the race must end in a five-way tie. None of the five speeds may be a multiple
of any of the others.

Activity 8-28: Pickles Will Kill You!
Name:
Numbers are all around us. People can use numbers in misleading ways. All of the numbers below are
true, so does that mean pickles will kill you?
Every pickle you eat brings you nearer to death. Amazingly, the "thinking man" has failed to grasp the
terrifying significance of the term "in a pickle." Although leading horticulturists have long known that
Cucumis sativus possesses an indehiscent pepo, the pickle industry continues to expand.
Pickles are associated with all the major diseases of the body. Eating them breeds war and communism.
They can be related to most airline tragedies. Auto accidents are caused by pickles. There exists a
positive relationship between crime waves and consumption of this fruit of the cucurbit family.
For example ...
•
•
•
•
•
•
Nearly all sick people have eaten pickles. The effects are obviously cumulative.
99.9% of all people who die from cancer have eaten pickles.
99.8% of all soldiers have eaten pickles.
96.8% of all communist sympathizers have eaten pickles.
99.7% of the people involved in air and auto accidents ate pickles within 14 days preceding the
accident.
93.1% of all juvenile delinquents come from homes where pickles are served frequently.
Evidence points to the long-term effects of pickle eating:
•
•
Of all the people born in 1869 who later dined on pickles, there has been a 100% mortality.
All pickle eaters born between 1879 and 1899 have wrinkled skin, have lost most of their teeth,
have brittle bones and failing eyesight -- if the ills of eating pickles have not already caused their
death.
Even more convincing is the report of a noted team of medical specialists: rats force-fed with 20 pounds
of pickles per day for 30 days developed bulging abdomens. Their appetites for wholesome food were
destroyed.
In spite of all the evidence, pickle growers and packers continue to spread their evil. More than 120,000
acres of fertile U.S. soil are devoted to growing pickles.
Eat orchid petal soup. Practically no one has as many problems from eating orchid petal soup as they do
with eating pickles.
