The median is a statistical measure that represents the middle value in a dataset. It is often used to give a quick and easy summary of the central tendency of a dataset, especially when the dataset is skewed or has outliers. Finding the median is relatively straightforward and can be done using a variety of methods.
The median is particularly useful when dealing with skewed data or data that contains outliers. For example, if you have a dataset of incomes, the mean income may be significantly higher than the median income due to the presence of a few very high incomes. In this case, the median would provide a more accurate representation of the typical income in the dataset.
