Statistics Calculator
Calculate mean, median, mode, range, and standard deviation from a dataset.
كيفية الاستخدام
- Enter your dataset into the text area. You can separate numbers with commas or spaces.
- Select whether your data represents a Sample or an entire Population (this changes the formula used for variance and standard deviation).
- The calculator instantly extracts all standard descriptive statistics including central tendencies (mean, median, mode) and dispersion (range, variance, std dev).

Mean: Sum of all values / Count
Median: The middle value when sorted (or average of two middle values)
Mode: The value(s) that appear most frequently
Range: Maximum - Minimum
Variance (Sample): Σ(x - Mean)² / (n - 1)
Std Deviation: √Variance
Median: The middle value when sorted (or average of two middle values)
Mode: The value(s) that appear most frequently
Range: Maximum - Minimum
Variance (Sample): Σ(x - Mean)² / (n - 1)
Std Deviation: √Variance
A comprehensive Statistics Calculator provides an instant summary of any dataset. Descriptive statistics like mean, median, and mode help you understand the "center" of your data, while range, variance, and standard deviation show how spread out the numbers are.
