Sample Size Calculator

The sample size calculator is an important tool used in statistics and research to determine the appropriate sample size required to ensure the accuracy and reliability of study results.

Why do we use it? 

The sample size calculator determines the minimum number of samples needed to meet your desired statistical constraints, considering key factors such as:

  • Is your data finite or infinite

For finite data:

  • Sample size
  • Population size

For infinite data:

  • Z score
  • Margin of error
