Z-Score Calculator

1. Raw Score (x): The value you are analyzing.
2. Population Mean (μ): The average of the group.
3. Standard Deviation (σ): The spread of the group.
4. Result: Get the Z-Score and the probability (percentile) associated with it.

The Z-Score Calculator determines how many standard deviations a data point is from the mean. It normalizes data, allowing you to compare scores from different datasets (like SAT vs ACT).

A positive Z-score means the value is above average; negative means below.
