Example
Calculating the Mean
Find the average of the data set: 12, 15, 20, 25.
- Sum all the values in the dataset: 12 + 15 + 20 + 25 = 72
- Count the total number of values: 4
- Divide the sum by the count: 72 / 4 = 18
- Result: The average is 18.
Frequently Asked Questions
The mean is the sum divided by the count. The median is the middle value when sorted. The median is less affected by outliers.
If every value appears the same number of times, there is no mode. This calculator will show "None" in that case.
Type your numbers separated by commas, spaces, or new lines. For example: 12, 45, 7, 98 or simply paste a column of numbers.
