Detailed explanation-1: -The median is the value in the middle of a data set, meaning that 50% of data points have a value smaller or equal to the median and 50% of data points have a value higher or equal to the median. For a small data set, you first count the number of data points (n) and arrange the data points in increasing order.

Detailed explanation-2: -The median is calculated by taking the “middle” value, the value for which half of the observations are larger and half are smaller. When there is a possibility of extreme values, the median is generally the better measure to use.

Detailed explanation-3: -The median of a data set is the middle value when the values are written in numerical order. If a data set has an even number of values, the median is the mean of the two middle values. The mode of a data set is the value that occurs most often.

Detailed explanation-4: -The median is the middle value in distribution when the values are arranged in ascending or descending order. The median divides the distribution in half (there are 50% of observations on either side of the median value). In a distribution with an odd number of observations, the median value is the middle value.
