Question

Find out Pearson’s coefficient correlation between the following X and Y series using

the deviation scores from their respective arithmetic mean. Interpret the results.

X : 15 20 25 30 35 40 45 50 55 60

Y : 35 36 30 30 25 25 20 20 15 15​

Answer 1

Answer:

Find the mean of all the x-values.

Find the standard deviation of all the x-values (call it sx) and the standard deviation of all the y-values (call it sy). ...

For each of the n pairs (x, y) in the data set, take.

Add up the n results from Step 3.

Divide the sum by sx ∗ sy.
