q 8.) the line plots compare the test scores for a first- & second - period math class. first - period class points second - period class points what is the range for both periods class points? answer_

Answer

Explanation:

Step1: Recall range formula

Range = Maximum value - Minimum value

Step2: Find max and min for first - period class

For first - period class, minimum value = 2, maximum value = 6.

Step3: Calculate range for first - period class

Range of first - period class = 6 - 2 = 4

Step4: Find max and min for second - period class

For second - period class, minimum value = 4, maximum value = 9.

Step5: Calculate range for second - period class

Range of second - period class = 9 - 4 = 5

Step6: Find overall range

To find the range considering both periods, we look at all the data points. The overall minimum value among all data points is 2 and the overall maximum value is 9. Range = 9 - 2 = 7
