Question

Which of the following affect the WIDTH of a confidence interval? (SELECT ALL THAT APPLY)

Confidence level

Sample size

Sample Mean

Standard deviation of the sample/population

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.
