Question

A given set of data has a sample size of 20, average of 20, and standard deviation of 4. Use this
information to calculate the raw scores from the Z scores provided in questions

1. Z = +2.5

2. Z = -1.0

3. Z = +0.0

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
