What is the Z-Score Calculator?

The Z-Score Calculator computes the z-score of a given value, which measures how many standard deviations the value is from the mean. By entering the value, mean, and standard deviation, the calculator quickly provides the z-score, helping users understand the relative position of a data point within a dataset. This tool is ideal for students, researchers, and anyone working with statistics, allowing easy assessment of data points, comparison across datasets, and identification of outliers.

How to Use:

1. Enter Value (X): Type the data point you want to analyze.
2. Enter Mean (μ): Input the average of the dataset.
3. Enter Standard Deviation (σ): Enter the dataset’s standard deviation. Make sure σ ≠ 0.
4. Click “Calculate”: The calculator displays the z-score for the given value.
5. Review the Result: Use the z-score to assess how far the value is from the mean, compare data points, or identify outliers.
