How to Use the Mean, Median, Mode & Range Calculator
-
1
Enter numbers separated by commas, spaces, or line breaks (e.g. `12, 15, 18, 15, 22, 30, 15`).
-
2
The calculator sorts your dataset and computes: Mean (Average), Median (Middle value), Mode (Most frequent), Range, and Count.
-
3
Inspect advanced statistics: Sample Variance ($s^2$), Population Variance ($sigma^2$), Standard Deviation, and Quartiles (Q1, Q3, IQR).
-
4
Review step-by-step arithmetic explanations.
Practical Example & Use Case
Analyzing test scores `75, 82, 90, 82, 68, 94` yields a Mean of 81.8, Median of 82.0, Mode of 82, and Range of 26.
Technical Notes & Limitations
Calculates high-precision floating-point statistics in browser memory.
Frequently Asked Questions
Can a dataset have more than one mode?
Yes. If two values share the highest frequency, the dataset is bimodal; if three or more, it is multimodal.
