Name: _____________________
Please show and include ALL work
Period: ____
CHECKLIST:
 Collect the following data from 9 students (everyone should have different data).
 Shoe size (girls will need to subtract two sizes so all the sizes will be in boys)
 Height in inches.
 Average number of hours spent sleeping week.
 Number of people in their household.
 Calculate the measure of central tendency (mean, mode and median) of each data collected
 Make a Dot Plot for the shoe size.
 Make a histogram for the number of people in their household
 List the five number summary and then make a Box and Whisker for average number of hours
slept each week
 Make a scatter plot comparing shoe size to height. Use the calculator to find the line of regression
and the correlation coefficient. Describe the correlation between data.
 Make a two-way table displaying the average number of hours slept by girl and boy. Convert the
two-way table to a relative frequency table by rows and then columns
