How to Use the Statistics Calculator
Enter a data set to compute mean, median, mode, range, variance, and standard deviation.
- Enter your numbers separated by commas or spaces.
- The calculator computes all summary statistics.
- Review measures of center and spread.
Key Statistics Formulas
Mean
Sum of values divided by the count.
Example:
Input: 2, 4, 6
Calculation: 12 / 3
Result: 4
Sample Variance
Average squared deviation, using nâ1 for a sample.
Example:
Input: 2, 4, 6
Calculation: (4+0+4)/2
Result: 4
Standard Deviation
Square root of the variance, in the original units.
Example:
Input: variance = 4
Calculation: â4
Result: 2
Real-World Use Cases
Data Analysis
Summarize a dataset before deeper analysis.
Quality Control
Track spread to detect process drift.
Tips
Tips
- Use sample (nâ1) statistics for a sample, population (n) for a full population.
- The median resists outliers better than the mean.
