What is overall range?

The lowest value from all the grades is 48. So, the overall range is 51 and this can be determined by using the formula of the range.

Given :

The given table shows both the highest score and the range of scores for the students in each of the grades.

The difference between the largest value and the lowest value in the given data is known as the range of the data.

First, determine the lowest score from each grade by using the highest score and the range.

The lowest value of grade 5 is:

87 - 37 = 50

The lowest value of grade 6 is:

91 - 31 = 60

The lowest value of grade 7 is:

96 - 48 = 48

The lowest value of grade 8 is:

99 - 29 = 70

So, from the above calculation, it can be concluded that the lowest value from all the grades is 48. So, the overall range is given by:

99 - 48 = 51

Step-by-step explanation:

Overall range is the difference between the maximum value and the minimum value.

Since we're given the highest value, 99, all we have to do is find the minimum value, so subtract each of the highest scores from the ranges in their designated row.

The lowest score (minimum value) of all grades is 48.

Subtract 99 from 48 to find the overall range of the chart.

99 - 48 = 51.

51 is the overall range of the History Challenge Chart.
