To find the median of a set of numbers, you first need to arrange them in numerical order. Once you have them in order, the median is the middle number. 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. In this case, the numbers arranged in numerical order are: 78, 81, 82, 88, 88, 88, 89, 91, 91, 92, 93, 94, 95, 96, 98. Since there are 15 numbers, the median will be the 8th number, which is 89.
Put them in order, least to greatest. 62, 78, 84, 89, 94, 94, 96, 98 The range is the smallest subtracted from the largest. 98 - 62 = 36 The range is 36. The median is the average of the middle two. 89 + 94 = 183 divided by 2 = 91.5 The median is 91.5
composite numbers 89-97 = 90, 91, 92, 93, 94, 95, 96
The median is 86.
90.
The range is 36 because 98-62=36. Hope this helps :)
94-89 = 5
