2. Below are two columns of numbers: values of x and y for five
observations. The next three columns have been left blank for you
to fill in. The variable x has a mean of 3.0 and a standard
deviation equal to 1.6. The variable y has a mean of 11.6 and a
standard deviation of 5.0. In this exercise you will hand-calculate
the Pearson’s correlation coefficient, R2, and adjusted R2 for the
relationship between x and y. x y Z Score of x Z Score of y Z Score
of x × Z Score of y 1 18 2 13 3 14 4 7 5 6 A.
A. Calculate and write in the appropriate values in each
column.
B. Show your calculation of Pearson’s r for the
relationship.
C. Calculate R2 for this relationship.
D. Showing your work, calculate adjusted R2 for this
relationship.
