Question

100%

Indicate the LEAST sample size required using the Yamane's formula.

1. Population = 500 margin of error = 1%

2. Population = 1200 margin of error = 5%

3. Population = 855 margin of error = 10%

4. Population = 450 margin of error = 5%

5. Population = 320 margin of error = 1%

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.
