Question

Find the minimum, maximum, range, mean, and median for the data set.

2.4, 2.6, 7.2, 5.5, 4.1, 5.5, 6.1, 6.1



A.


minimum: 2.4

maximum: 7.2

range: 4.8

mean: 5.5

median: 4.9


B.


minimum: 2.4

maximum: 7.2

range: 9.6

mean: 4.9

median: 5.5


C.


minimum: 7.2

maximum: 2.4

range: 4.8

mean: 4.9

median: 5.5


D.


minimum: 2.4

maximum: 7.2

range: 4.8

mean: 4.9

median: 5.5

Answer 1

minimum: the lowest value from the set

2.4

maximum: the largest value from the set

7.2

range: maximum - minimum

7.2 - 2.4 = 4.8

mean: the average of the values

(2.4 + 2.6 + 7.2 + 5.5 + 4.1 + 5.5 + 6.1 + 6.1) / 8 = 4.9

median: the middle value when the set is arranged in order

5.5


Therefore, the correct answer is option D.

Answer 2

minimum: 2.4

maximum: 7.2

range: maximum - minimum = 7.2 - 2.4 = 4.8

mean: = (2.4 + 2.6 + 7.2 + 5.5 + 4.1 + 5.5 + 6.1 + 6.1) / 8 = 4.9

median: median is the middle number after the dataset is arranged in order (i.e. 2.4, 2.6, 4.1, 5.5, 5.5, 6.1, 6.1, 7.2). median = 5.5.
