Detailed explanation-1: -The median is usually preferred to other measures of central tendency when your data set is skewed (i.e., forms a skewed distribution) or you are dealing with ordinal data.
Detailed explanation-2: -The mean is used for normal number distributions, which have a low amount of outliers. The median is generally used to return the central tendency for skewed number distributions.
Detailed explanation-3: -The median is less affected by outliers and skewed data than the mean and is usually the preferred measure of central tendency when the distribution is not symmetrical.
Detailed explanation-4: -When the dataset contains an even number of values, then the median value of the dataset can be found by taking the mean of the middle two values.
Detailed explanation-5: -The median is a better measure of the central tendency of the group as It it is not skewed by exceptionally high or low characteristic values.
