Explanation:
Detailed explanation-1: -The median is the middle value in a set of data. First, organize and order the data from smallest to largest. To find the midpoint value, divide the number of observations by two. If there are an odd number of observations, round that number up, and the value in that position is the median.
Detailed explanation-2: -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.
Detailed explanation-3: -The “center” of a data set is also a way of describing location. The two most widely used measures of the “center” of the data are the mean (average) and the median.
