Terms to know.
1) mean
A middle value for a set of numbers. It is found by adding the numbers in the set and
dividing the sum by the number of numbers.
Ex. Math scores: 85%, 95%, 100%, 88%, 80%, 92%. Add them up = 540.
Divide that by the number of scores (6). 540/6 = 90%
2) median
The middle value in a set of data when the data is listed in order from smallest to largest.
If there is an even number of data points, the median is halfway between the 2 numbers.
Ex. Math scores: 85%, 95%, 100%, 88%, 80%, 92%.
First list in order. Math scores: 80%, 85%, 88%, 92%, 95%, 100%.
88% and 92% are the middle numbers so the halfway point would be 90%.
3) mode
The value or values that occur most often in a set of data.
Ex. Math scores: Math scores: 100%, 95%, 100%, 88%, 80%, 92%.
100% occurs the most often in this set of data.
4) minimum
The smallest amount or the least number in a set of data.
Ex. Math scores: 85%, 95%, 100%, 88%, 80%, 92%.
80% is the minimum in this
set.
5) maximum The largest amount or the greatest number in a set of data.
Ex. Math scores: 85%, 95%, 100%, 88%, 80%, 92%.
this set.
6) range
100% is the maximum in
The difference between the minimum and the maximum in a set of data.
Ex. Math scores: 85%, 95%, 100%, 88%, 80%, 92%.
The minimum is 80%; the maximum is 100%. The range would be 20%.
7) perimeter The distance around a two-dimensional shape.
2"
A formula for a parallelogram is P = 2 * (length + width)
Ex. This parallelogram is 2" by 3" .
3"
Either add all sides: 2 + 3 + 2 + 3 = 10" or 2 * ( 2" + 3") = 10"
8) area
The measure of a surface inside a boundary.
The formula for measuring the area of a rectangle is Area = Length * Width.
6"
Ex. Area = 6" X 2" = 12 square inches or 12 ".
2"
