What is Z-Score Calculator?
The Z-Score Calculator is a statistical tool that helps determine how many standard deviations a data point is from the mean. It’s widely used in data analysis to standardize values, compare different datasets, and understand outliers.

Z-Score Calculator - Frequently Asked Questions
What is Z-Score Calculator?
The Z-Score Calculator is a tool that calculates the Z-score for a given data point, which shows how far that data point is from the mean of a distribution in terms of standard deviations.
How to Use Z-Score Calculator Website?
To use the Z-Score Calculator, simply input the following:
- The data point (X) for which you want to calculate the Z-score.
- The mean (μ) of the dataset or population.
- The standard deviation (σ) of the dataset or population.
What is the Formula of Z-Score Calculator?
The formula for calculating the Z-score is:
Z = (X - μ) / σ
Where:
- X: The data point for which the Z-score is being calculated.
- μ: The mean of the dataset or population.
- σ: The standard deviation of the dataset or population.
Advantages of Z-Score Calculator
- Helps in understanding how far a data point is from the mean.
- Used in hypothesis testing, data normalization, and identifying outliers.
- Standardizes different data sets, making comparisons easier.
Disadvantages of Z-Score Calculator
- The Z-score is sensitive to outliers in the data, which may distort the results.
- It assumes a normal distribution of the data, which may not always be the case.
