Place the values in ascending order: 76, 81, 89, 91, 97, 99. There are 2 middle numbers; 89 & 91. The median is the mean of the 2 middle numbers; or (89+91)/2 or 90.
91.57
The mean of any set of numbers is the sum of those numbers divided by how many numbers there are. Here, the sum is 99+97+91+89+81+76=533. When you divide 533 by 6 (the total number of numbers), you get 88.83333... repeating forever. In mixed number form, this is 88 and 5/6.
(79, 81, 82, 91, 93, 95, 95) The mean is 88 The mode is 95 The median is 91
83.7
That's an infinite list. 81, 83, 85, 87, 89, 91 and so on.
Mean = (88 + 85 + 91)/3 = 264/3 = 88
