Answer :
Set B has the greatest spread.
What is data set?
A data set is a collection of numbers or values that relate to a particular subject. For example, the test scores of each student in a particular class is a data set.
Given data set
Set A – {84, 91, 87, 77, 94, 89, 74}
Set B – {89, 73, 84, 91, 87, 77, 94}
Set C – {73, 84, 89, 88, 77, 91, 87, 90}
Set D – {84, 89, 88, 82, 91, 87, 99}
To find the greatest spread, Subtract the smallest value from a largest value of data set.
Set A – {84, 91, 87, 77, 94, 89, 74}
= 94 - 77
= 17
Set B – {89, 73, 84, 91, 87, 77, 94}
= 94 - 73
= 21
Set C – {73, 84, 89, 88, 77, 91, 87, 90}
= 91 - 73
= 18
Set D – {84, 89, 88, 82, 91, 87, 99}
= 99 - 82
= 17
So, set B has the greatest spread.
