Learn more about Bing search results hereOrganizing and summarizing search results for youThe sample size formula is given by:- n = Z² * p(1 - p) / m²
Where: - n = sample size
- Z = z-value (e.g., 1.96 for 95% confidence level)
- p = estimated proportion of the population (commonly set at 0.5 for maximum variability)
- m = margin of error (the desired precision)
Example: If you want to estimate the proportion of a population with a 95% confidence level (Z = 1.96), a margin of error of 5% (0.05), and you assume the population proportion (p) is 0.5, the calculation would be:
- n = (1.96)² * 0.5(1 - 0.5) / (0.05)²
- n = 3.8416 * 0.25 / 0.0025
