Calculate the correlation coefficient r. letting row 1 represent the x-values and row 2 the y-values. Then calculate it again, letting row 2 represent the x-values and row 1 the y-values. Whaqt effet does switching the variables have on r?
Row 1: 16 30 38 45 53 62 80
Row 2: 144 131 131 201 162 190 134
Calculate the correlation coefficient r, letting row 1 represent the x-values and row 2 the y-values.
r = ______ round to three decimal places as needed
Calculate the correlation coefficient r, letting row 2 represent the x-values and row 1 the y-values.
r = ______ round to three decimal places as needed
What effect does switching the variables have on the correlation coefficient?
The correlation coeficient ___________ when the x-values and y-values are switched.
Please show work in simplified terms for understanding. Thank you!
