Question

The number of burgers sold on seven days in a cafetaria is given.


Which of the following gives the mode and the range of the data set?

• A. 50, 60
• B. 60, 80
• C. 70, 90
• D. 50, 70

Answer 1

The correct option is A 50, 60

The data set from the given graph is

20, 50, 40, 70, 55, 50, 80

The mode of the data set is the value or values that occur most often.

Hence, mode = 50

Range = Maximum value - Minimum value

Arranging the data in ascending order, we get

20, 40, 50, 50, 55, 70, 80

Range = 80 - 20 = 60

Hence, mode and range of the dataset are 50 and 60, respectively.
