# What is the Median?

The median is a statistical measure used to find the middle value in a set of numbers when the data is ranked in ascending or descending order. It is a simple and reliable way to understand the central tendency of a distribution.

To calculate the median, first, arrange the data in numerical order. If there is an odd number of observations, the median is the middle value. For example, if you have a dataset of numbers {1, 2, 3, 4, 5}, the median would be 3.

If there is an even number of observations, the median is typically found by taking the average of the two middle values. For instance, if you have a dataset of numbers {1, 3, 5, 7}, the median would be (3 + 5) / 2 = 4.

The median is distinct from the mean, which is calculated by summing all the values in the dataset and dividing it by the number of observations. While the mean can be influenced by extreme values, the median provides a better representation of the typical or central value.

The median is used in various fields such as market research, data analysis, and epidemiology to summarize data and make informed decisions. It helps to identify the middle value in a dataset, allowing us to understand the distribution better and detect any outliers that might affect the overall analysis.

Understanding the median is essential to get a comprehensive grasp of statistics. By applying this simple measure, we gain valuable insights into the data and make more accurate interpretations.

## Importance of Assessing Candidates' Knowledge of Median

Evaluating a candidate's understanding of median is crucial in selecting the right fit for your organization. Here's why:
