## Median Calculator Instructions

This calculator computes the median from a data set:

To calculate the median from a set of values, enter the observed values in the box above. Values must be numeric and may be separated by commas, spaces or new-line. You may also copy and paste data into the text box. You do not need to specify whether the data is from a population or a sample, unless you will later examine the variance or the standard deviation. Press the "Submit Data" button to perform the computation. To clear the calculator and enter a new data set, press "Reset".

### What is the median

The median is a **measure of central tendency**. It represents the value for which 50% of observations a lower and 50% are higher. Put simply, it is the value at the center of the sorted observations.

### Median formulas

This calculator uses two different formulas for calculating the median, depending on whether the number of observations is odd, or it is even:

__When the number of observations is odd__ the formula is:

__When the number of observations is even__ the formula is:

where n is the number of observations.
