Question

The table lists the number of laps Maria swam daily for 6 days. What is the median of the number of laps she swam?

A.
10
B.
11
C.
12
D.
13
E.
14

Answer 1

The correct answer option is D. 13.

Explanation:

We have the following data set for the number of laps Maria swam daily for 6 days:

16, 6, 8, 12, 14, 14

To find the median, we first need to sort the data in an ascending order:

6, 8, 12, 14, 14, 16

Now since the number of elements is an even number i.e. 6, we will take the two middle values and take their mean to find the median.

Median =
`(12+14)/(2)`

Median =
`(26)/(2)`
`= 13`

Therefore, 13 is the median for the given data set.

Answer 2

Answer: Option D. 13

Solution:

The data is:

16, 6, 8, 12, 14, 14

1) Sort the data from the least to the greatest:

6, 8, 12, 14, 14, 16

2) Find the median (middle value)

6, 8, 12, 14, 14, 16

1 2 3 4 5 6

We have to middle values, the third and fourth values (12 and 14), then the median is the average of these two values:

Median=(12+14)/2

Median=(26)/2

Median=13
