Question

given:

RPE Treadmill X axis values: 18,17,14,12,10

RPE Cycling Y axis values: 17,16,13,14,11

1.) Calculate the degrees of freedom for this correlation test and determine the critical r from the table on the equation sheet.

2.) Calculate the Pearson’s Product Moment Correlation Coefficient r for the sample RPE data.

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
