. A sample of n = 16 scores has a mean of M = 56 and a standard deviation of s = 12. a. Explain what is measured by the sample standard deviation. b. Compute the estimated standard error for the sample mean and explain what is measured by the standard error.

Step 1
The sample standard deviation (s) measures the average amount of variability or dispersion in the scores of the sample. It gives us an idea of how spread out the scores are from the mean (M). In this case, the sample standard deviation is s = 12. b. The estimated Show more…

A sample of $n=16$ scores has a mean of $M=56$ and a standard deviation of $s=20$ a. Explain what is measured by the sample standard deviation. b. Compute the estimated standard error for the sample mean and explain what is measured by the standard error.
A sample of $n=16$ individuals participates in a repeated-measures study that produces a sample mean difference of $M_{D}=6.45$ with $S S=960$ for the difference scores. a. Calculate the standard deviation for the sample of difference scores. Briefly explain what is measured by the standard deviation. b. Calculate the estimated standard error for the sample mean difference. Briefly explain what is measured by the estimated standard error.
