Using the Formula n=1M?E2
to Determine Sample Size
When we want 95% confidence and use the conservative estimate of p = 0.5, we can use the simple formula n=1M?E2
to roughly determine the sample size needed for a given margin of error ME. Use this formula to determine the sample size needed for a margin of error of 0.02 .
Enter the exact answer. n=
