Mean, Median, Mode Calculator

This calculator helps you analyze a set of numbers by computing the mean (average), median, and mode, along with other statistics like range, minimum, maximum, count, and sum.

How to Use the Calculator

1. Enter your data as comma-separated numbers into the text box (e.g., 9, 10, 12, 13, 15).

2. Click the “Calculate” button.

3. View results for mean, median, mode, and more.

4. Click “Clear” to reset the input and start over.

Formulas Used:

1. Mean (Average)

$$\bar{x}=\frac{\sum x_i}{\mathrm{n<span\; class="vlist"\; style="font-family:\; Verdana,\; BlinkMacSystemFont,\; -apple-system,\; \text{'}Segoe\; UI\text{'},\; Roboto,\; Oxygen,\; Ubuntu,\; Cantarell,\; \text{'}Open\; Sans\text{'},\; \text{'}Helvetica\; Neue\text{'},\; sans-serif;\; color:\; initial;"></span>}}$$Where:

• $\sum x_i$ = sum of all values

• $n$ = total number of values

2. Median

• If $n$ is odd, median is the middle number.

• If $n$ is even, median is:

$$\text{Median}=\frac{x_{\left(\frac{n}{2}\right)}+x_{(\frac{n}{2}+1)}}{2}$$

3. Mode

• The number(s) that appear most frequently in the dataset.

4. Range

$$\text{Range}=\text{Maximum}-\text{Minimum}$$

Example:

Input:
9, 10, 12, 13, 13, 13, 15, 15, 16, 16, 18, 22, 23, 24, 24, 25

Results:

• Mean: 16.75
