To find the mean, add the numbers (84 + 85 + 88 + 89 + 82 + 78 + 82) to get 508, then divide by 7, resulting in a mean of approximately 72.57. The median is the middle value when the numbers are arranged in order (78, 82, 82, 84, 85, 88, 89), which is 84. The mode is the number that appears most frequently, which is 82. The range is the difference between the highest (89) and lowest (78) values, giving a range of 11.
The median is 84.
