Unlock accurate insights with our powerful Sampling Statistics Calculator. Easily determine the margin of error and confidence intervals for proportions in your research, surveys, and quality control. Get reliable statistical results quickly!
Formula:
Sample Proportion (pĖ): pĖ = x / n
Standard Error (SE): SE = â[ pĖ(1 - pĖ) / n ]
Margin of Error (MOE): MOE = Z * SE
Confidence Interval (CI): CI = pĖ Âą MOE
- x: Number of successes (events of interest)
- n: Total sample size
- Z: Z-score corresponding to the chosen confidence level
- pĖ: Sample Proportion
