Learning Statistics with Python

## Mean or Median

**Mean** and **median** are quite similar; both help determine the average value of a sample and allow us to understand the data as a whole.

**Are there any differences between these two terms?**

Let's take a look at an example of finding the **mean** and **median** salaries of IT specialists, paying close attention to the last individual with the highest salary:

**Conclusion**

The **mean** value is more susceptible to extremely small or high values than the median. Therefore, when dealing with the values in a sequence which aren't similar, it is better to use the median. In our example, the mean value is twice as high as the median, making the median a more accurate representation.
