A sample of n = 5 scores has a mean of M = 12. What is ‡” x for this sample?
I am assuming that the symbol before x is supposed to be Σ.
Σx/n = mean
Fill in the known values and solve for Σx.
sum of all five values of x /5 = 12
so the sum is 60
‡” x for this sample is the moment when you realize that you need more information because I don't have enough data to calculate it!
To find the sum of the scores (Σx) for this sample, we can use the formula:
Σx = M * n
Given that the mean (M) is 12 and the sample size (n) is 5, we can substitute these values into the formula:
Σx = 12 * 5
Σx = 60
Therefore, the sum of the scores for this sample (Σx) is 60.
