About Average Calculator
Enter a set of numbers to calculate comprehensive statistics: arithmetic mean, median, mode, range, sum, count, variance, and standard deviation. Handles decimal numbers and large data sets.
How It Works
Enter numbers separated by commas, spaces, or newlines. The tool sorts the values and calculates all statistical measures. For mode, it finds the most frequently occurring value(s).
Step by Step
- 1 Enter numbers separated by commas, spaces, or newlines
- 2 Click Calculate to see all statistics
- 3 Review mean, median, mode, range, and standard deviation
Tips
- Mean is affected by outliers; median is more robust
- A data set can have multiple modes or no mode
- Standard deviation measures how spread out the values are
- Paste data from spreadsheets — the tool handles various separators
Frequently Asked Questions
What is the difference between mean and median?
Mean is the arithmetic average (sum / count). Median is the middle value when sorted. Median is better for skewed data because outliers don't affect it.
When should I use standard deviation?
Use standard deviation to measure data spread. A low value means data points are close to the mean; a high value means they're spread out.
