Answer:
Mean: 85
Median: 82
Mode: 82
Range: 25
Step-by-step explanation:
The mean is the average of all of the numbers. You add all of the numbers together and then divide by the total amount of number you have. In this case you have 8 scores. So you add all the scores together, and then divide by 8:
82 + 78 + 82 + 80 + 100 + 96 + 75 + 91 = 684
684/8 = 85.5
So 85 is the mean.
The median is the number that is in the middle of all of the numbers listed. To do this, first list the numbers in order:
75, 78, 80, 82, 82, 91, 96, 100
The two numbers in the middle are both 82. So, 82 is the median.
The mode is the number that appears the most. In this problem, you can see that the number 82 appears twice. So 82 is the mode.
The range is the highest number minus the smallest number. Here, the highest number is 100. The smallest number is 75. So,
100 - 75 = 25
25 is the range.
