Sample Size Calculator for 2 Sample T Test (Finite Population)

Hint: Use this calculator to determine the number of samples required to compare two population means if you have a finite population (i.e. less than 50000)

Confidence Level
The minimum acceptable probability of preventing type I error
- 90%
- 95%
- 99%
- 99.9%
Power of the Test
The minimum acceptable probability of preventing type II error
- 50%
- 80%
- 90%
- 95%
- 99%
Mean 1
Enter the 1st population or sample mean
Mean 2
Enter the 2nd population or sample mean
Population Standard Deviation
This is the common standard deviation of the two populations or samples (also known as the pooled standard deviation)
Finite Population
Enter a number less than 50,000
