A set of n = 5 pairs of X and Y values has SX = 10, SY = 20, and SXY = 10. For this set of scores, what is the value of SP?

A set of n = 5 pairs of X and Y values has SX = 10, SY = 20, and SXY = 10. For this set of scores, what is the value of SP?

To find the value of SP (the sum of products), we need to know the formula for SP. The formula for SP is:

SP = SXY - (SX * SY) / n

Where:
- SXY is the sum of the products of X and Y
- SX is the sum of X values
- SY is the sum of Y values
- n is the number of pairs of X and Y values

Given:
- n = 5
- SX = 10
- SY = 20
- SXY = 10

We can substitute these values into the formula to calculate SP:

SP = SXY - (SX * SY) / n
= 10 - (10 * 20) / 5
= 10 - 200 / 5
= 10 - 40
= -30

Therefore, the value of SP for this set of scores is -30.
