Question
The ages of a group of 10 people are as follows: 25,
28, 30, 32, 35, 35, 38, 40, 42, and 45. Calculate the mean and median age of this group.Solution
Mean (Average) = (Sum of all ages) / (Number of people) Mean = (25 + 28 + 30 + 32 + 35 + 35 + 38 + 40 + 42 + 45) / 10 Mean = 350 / 10 Mean = 35 To calculate the median, first, arrange the ages in ascending order: 25, 28, 30, 32, 35, 35, 38, 40, 42, 45. Since there are 10 numbers, the median will be the average of the 5th and 6th numbers, which are both 35. Median = (35 + 35) / 2 Median = 35
