How to Use This Calculator
Enter your numbers separated by commas in the input field (e.g. 10, 20, 30, 40, 50). The calculator instantly shows the mean, median, mode, count, and sum.
Formula
Mean = Σx / n • Median = middle value when sorted • Mode = most frequent value
Example
10, 20, 30, 40, 50 → Mean=30, Median=30, No mode, Sum=150
Frequently Asked Questions
- Mean is the arithmetic average. Median is the middle value when sorted. Mode is the most frequent value.
- Use the median when your data has outliers, such as income data where a few very high values would skew the mean.
- If all values appear exactly once, there is no mode. The calculator will display "No mode".
- Yes — if two or more values tie for the highest frequency, all of them are modes. This is called bimodal or multimodal.
- Type or paste numbers separated by commas in the input field, e.g. 10, 20, 30, 40, 50.
