Explanation:
Detailed explanation-1: -The two most widely used measures of the “center” of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50. To find the median weight of the 50 people, order the data and find the number that splits the data into two equal parts.
Detailed explanation-2: -Median. The median of a data set is the value that is at the middle of a data set arranged from smallest to largest. In the data set 1, 2, 3, 4, 5, the median is 3. In a data set with an even number of observations, the median is calculated by dividing the sum of the two middle values by two.
