# Free Online Median Calculator

Before using our compound interest calculator, it might help to know what it is and why this important. If you’re already familiar with the concept, then feel free to scroll down to the calculator below.

The median is a measure of central tendency that represents the middle value in a set of data when the data is sorted in ascending or descending order. If the dataset contains an odd number of observations, the median is the middle number. If the dataset contains an even number of observations, the median is the average of the two middle numbers. Unlike the mean, the median is not affected by outliers or extreme values, making it a more robust measure of central tendency in datasets where such values might skew the mean.

The median is particularly useful in understanding the ‘typical’ value in a dataset where the data may not be symmetrically distributed, i.e., skewed distributions. For example, in economics, the median is often used to understand income distribution, as high-income outliers can significantly skew the mean, making it less representative of the typical income. In real estate, the median home price is often reported as it provides a more accurate picture of the typical house price in an area, as the mean could be skewed by a few very high-priced properties. Thus, the median can provide a more representative ‘central’ or ‘typical’ value in certain datasets, especially those with outliers or skewed distributions.

1

### Input Your Data

You'll see a text input field labeled "Enter numbers separated by commas". Input your dataset here. Your dataset should be a list of numbers, each separated by a comma. For example, to find the median of the numbers 5, 3, 9, and 11, you would input "5,3,9,11".

### Calculate the Median

After inputting your data, click on the button labeled "Calculate Median". This action triggers the JavaScript function calculateMedian(). This function splits your input into individual numbers, sorts them in ascending order, and then determines the median. If there is an even number of numbers, the median is the average of the two middle numbers. If there is an odd number of numbers, the median is the middle number.

### View the Result

The median of the dataset you entered will be displayed below the "Calculate Median" button. The result will be displayed as "Median: x", where x is the calculated median value. If you want to calculate the median for a new dataset, simply clear the input field, enter the new data, and click "Calculate Median" again.
