Question

A sample of n=4 scores has SS=108
-Compute the estimated standard error for the sample mean.

Answer 1

The estimated standard error for the sample mean, given SS=108 and n=4, is calculated using the formula and the result is 3.

Step-by-step explanation:

To compute the estimated standard error for the sample mean when you have SS (sum of squares) and the sample size n, you can use the formula:

Standard error (SE) = √(SS / n(n-1))

Here, n = 4 and SS = 108. Plugging these values into the formula, we get:

SE = √(108 / 4(4-1))
= √(108 / 12)
= √9
= 3

Therefore, the estimated standard error for the sample mean is 3.

The estimated standard error for the sample mean can be calculated using the formula:

Standard Error = Square root of (Sum of Squares / (n - 1))

In this case, the Sum of Squares (SS) is given as 108 and the number of scores (n) is 4. Plugging these values into the formula:

Standard Error = Square root of (108 / (4 - 1)) = Square root of 36 = 6.
