How to Use the Statistics Calculator

Our statistics calculator provides comprehensive statistical analysis of your data with instant results:

📊 Basic Statistics

Mean (Average): Sum of all values divided by the number of values
Median: Middle value when data is arranged in order
Mode: Most frequently occurring value(s)
Range: Difference between maximum and minimum values

📈 Advanced Statistics

Standard Deviation: Measure of data spread from the mean
Variance: Average of squared differences from the mean
Sum: Total of all data values
Count: Number of data points

💡 Data Input Tips

• Separate values with commas: 10, 15, 20, 25
• Use spaces: 10 15 20 25
• Enter one value per line
• Decimal numbers are supported: 10.5, 15.7
• Negative numbers are allowed: -5, 10, -15

Frequently Asked Questions

Mean is the average of all values (sum ÷ count), while median is the middle value when data is sorted. Median is less affected by extreme values (outliers) than mean.
Standard deviation measures how spread out data points are from the mean. It's calculated as the square root of variance. Lower values indicate data points are closer to the mean.
If multiple values appear with the same highest frequency, all of them are considered modes. Our calculator will display all mode values separated by commas.
Yes! Our calculator supports negative numbers, decimal numbers, and zero. All statistical calculations work with any real numbers.
There's no strict limit, but for optimal performance, we recommend keeping datasets under 10,000 values. Larger datasets may take longer to process.
