Question
The following are scores made on a math test: 80, 90, 90, 85, 60, 70, 75, 85, 90, 60, 80. The range of these scores is
- 30
- 70
- 90
- 75
Hint:
The range in statistics for a given data set is the difference between the highest and lowest values.
The correct answer is: 90
Step 1 of 1:
Given a set of numbers: 80, 90, 90, 85, 60, 70, 75, 85, 90, 60, 80
Observe that, the lowest number = 60 and the highest number = 90
So, range = 90 - 60 = 30
Final Answer:
The range of these scores is-- b. 30
