Question

Over the first five years of owning her car, Gina drove about 12,700 miles the first year, 15,478 miles the second year, 12,675 the third year, 11,850 the fourth year, and 13,075 the fifth year. Find the mean, median, and mode of this data.

Answer 1

mean = 13,156; median = 12,700; no mode

Answer 2

Mean = 13,155.6

Median = 12,700

Mode: No mode

Explanation:

Gina drove her car over first five years.

12,700 15,478 12,675 11,850 13,075

We need to find mean, median and mode

Mean: It is value of sum of all observation over number of observation.

Mean
`=(12700+15478+12675+11850+13075)/(5)`

Mean
`=(65778)/(5)`

Mean = 13,155.6

Median: It is middle value of the arrange data.

First we arrange the given data into acceding order.

11,850 12,675 12,700 13,075 15,478

Total number of data = 5

Middle term = 3

Median = 12,700

Mode: It is value of the observation which repeated maximum number of times.

Here no value repeat more than one time.

Hence, No mode for this data
