How to Use This Calculator
- Enter the mean (μ) value.
- Enter the standard deviation (σ) value.
- Enter the Z-score value.
- Click the ‘Calculate’ button.
Formula & Methodology
The formula for the normal distribution is f(x) = (1 / (σ * sqrt(2 * π))) * e^(-((x – μ) / (2 * σ^2))). The Z-score is calculated as (X – μ) / σ…
