Sample Size Calculator For 2 Proportion Test (Finite Population)

Hint: Use this calculator to determine the number of samples required to compare two population proportions if you have a finite population (i.e. less than 50000)
  • The minimum acceptable probability of preventing type 1 error
  • The minimum acceptable probability of preventing type 2 error
  • Enter the first population proportion. For 50%, just enter 50
  • Enter the first population proportion. For 50%, just enter 50
  • Minimum samples required to check if the two proportions are similar or not
  • Enter a number less than 50,000
  • Minimum samples required to check if the two proportions are similar or not for the given finite population
