Question

What is the range of 61 59 60 50 54 56 61 63 and 98 90 92 78 83 88 95 98

Answer 1

What is the range?

The range is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The range is easily calculated by subtracting the lowest from the highest value in the set.

Range Formula:

The formula for the range is:

Range = maximum(xi) - minimum(xi)

where xi represents the set of values.

Substitute the values in:

Range= 98-50= 48

Range= 48

Separate sets range:

First set:

63-50= 13

Second set:

98-78= 20

(Credits to the second answer)

Answer 2

To calculate the range, you need to find the largest observed value of a variable (the maximum) and subtract the smallest observed value (the minimum).

Set A:

50, 54, 56, 59, 60, 61, 61, 63

63 - 50 = 13

Set B:

78, 83, 88, 90, 92, 95, 98, 98

98 - 78 = 20

Range of Both Sets:

98 - 50 = 48
