Question

The maximum weights (in kilograms) for which one repetition of a half squat can be performed and the times (in seconds) to run a 10-meter sprint for 12 international socoer players are shown in the attached data table with a sample correlation coefficient r of 0.956. A 13th data point was added to the end of the data set for an intemational soccer player who can perform the half squat with a maximum of 210 kilograms and can sprint 10 meters in 2.01 seconds. Describe how this affects the correlation coefficient r.

Explanation / Answer

The statistical software output for this problem is:

Correlation between x and y is:
-0.63532608

Hence,

The new correlation coefficient r decreases (Not sure about this one because i dont know the options available in dropdown) going from -0.956 to -0.635
