The sample size n can be calculated using the following formula.
For each value of alpha we can calculate two. Step 1 - Enter the Sample Size n Step 2 - Enter the Sample Standard Deviation s. Chi-Squared test For variance calculator Degrees of freedom - the total number of observations minus one. N 423 patients.
