Sample Size Calculator by Creative Research Systems is a comprehensive tool that allows you to calculate sample sizes for different study designs. Here's how you can use it:

The formulas for calculating sample size depend on the statistical method used. Here are the commonly used formulas: Power analysis: N = [ (Zα/2 + Zβ) / ES] ^ 2. Where: N = sample size. Zα/2 = the critical value of the standard normal distribution for a specified level of significance.

Quick tests: Traditional research agencies might only recommend a sample size of 100-150 (n=100-150). This is due to them taking much longer to fill surveys. At Attest, we recommend n=250 per cell because we can fill surveys much quicker which gives you robustness and confidence in the results you get back!
