📘 About This Calculator
This calculator uses the Krejcie & Morgan (1970) formula to estimate the minimum sample size required when the total population size is known. It is commonly used in social sciences, education, and health research.
The formula is:
n = (X² × N × P × (1 − P)) / (d² × (N − 1) + X² × P × (1 − P))
- X² = 3.841 (for 95% confidence level)
- P = 0.5 (maximum variability)
- d = 0.05 (±5% precision)
