Explanation

2,2,3,3,3,4,4,4,4,5,5,5,7,8,9,9. = 4To find the median of a set of numbers, we arrange the numbers in ascending order and then determine the middle value. If there is an odd number of values, the median is the middle number. If there is an even number of values, the median is the average of the two middle numbers.Arranging the given numbers in ascending order: 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 7, 8, 9, 9Since there are 16 numbers in the set, which is an even number, we need to find the average of the two middle numbers.The two middle numbers are the 8th and 9th numbers: 4 and 4.To find the median, we take the average of these two numbers:Median = (4 + 4) / 2 = 8 / 2 = 4Therefore, the median of the given set of numbers is 4.
