A population of N=6 scores ha EX=12 and Ex squared=54. What is the value of SS for this popluation

I have no idea what EX is.

To calculate the sum of squares (SS) for a population, we need to use the formula:

SS = Σ(X - μ)^2

Where:
- Σ represents the sum of the values.
- X represents each score in the population.
- μ represents the mean (average) of the population.

In this case, we are given:

N = 6 (the number of scores)
EX = 12 (the sum of all scores)
EX² = 54 (the sum of the squared values)

First, we need to calculate the mean (μ):

μ = EX / N

μ = 12 / 6

μ = 2

Now, we can calculate the sum of squares (SS):

SS = Σ(X - μ)^2

To do this, we need each individual score in the population. However, since the scores are not provided, we are unable to calculate the specific value of SS for this population. The given information does not allow us to determine the sum of squares without knowing the individual scores.
