Sample Size Calculator For 1 Sample T Test (Finite Population)

Hint: Use this calculator to determine the number of samples to compare the mean of a population with a standard, expected or target value if you have a finite population (i.e. less than 50000)

Confidence Level

Reference Mean Value
This is the standard or target or the known mean
Sample Standard Deviation
This is the known or estimated (from research) or the sample standard deviation
Sample Mean Value
This is the mean of the sample (in question)
