Which data set has the greatest spread ?
2 answers:
Answer:
(B) set B
Step-by-step explanation:
The greatest spread is the range of the given data set.
(A) The given data set is:
84,91,87,77,94,89,74
Arranging the given data in ascending order, we have
77, 77, 84, 87, 89, 91, 94
The range is given as:
Thus, the spread of the given data is 20.
(B) The given data set is:
89,73,84,91,87,77,94
Arranging the given data in ascending order, we have
73, 77, 84, 87, 89, 91, 94
The range is given as:
Thus, the spread of the given data is 21.
(C) The given data set is:
73,84,89,88,77,91,87,90
Arranging the given data in ascending order, we have
73, 77, 84, 87, 88, 89, 90, 91
The range is given as:
Thus, the spread of the given data is 18.
(D) The given data set is:
84,89,88,82,91,87,99
Arranging the given data in ascending order, we have
82, 84, 87, 88, 89, 91, 99
The range is given as:
Thus, the spread of the given data is 17.
Therefore, set B has the greatest spread that is 21.
