AP Statistics Summer Assignment
Read through the Explorations Activities and familiarize yourself with the calculator. Work on
each activity as written and make sure you know how to use the functions on your TI-83+/84+.
Using the activities as a guide, use the data below to create the graphs and charts requested.
This should be handed in on the first full day of class. On the first full Friday of school, you will
have a quiz to test your knowledge of the graphing calculator; more will be explained when
school starts. Good luck – email me if you have questions at Jeannette.Wilt@bsd.k12.de.us

Enter the data in your graphing calculator and save it as a list named IQ. Use the data to
answer the following on a separate page. Use graph paper and be neat!
a) On a separate page, construct a frequency table for these IQ scores, with a class width
of size 10.
b) Calculate the relative frequencies for each class and list them in the next column on the
frequency table.
c) Calculate the cumulative relative frequencies for each class and list them in the final
column on the table.
d) Draw a relative frequency histogram for the data.
e) Draw a cumulative relative frequency graph (ogive) for the data.
f) Draw a stemplot (stem-and-leaf plot) for the data.
g) Draw a boxplot (box-and-whisker plot) for the data. List the 5-number summary.
Copy this chart onto a separate page to answer parts 1 a-c.

a) Construct a scatterplot for these data on graph paper. Describe the relationship between
the 2 variables.
b) Determine the equation of the least-squares regression line for predicting heart disease
death rate from wine consumption using these data. Interpret the slope and y-intercept
in the context of the problem.
