Question

The 8 students in Mrs. Brown's class were asked how many minutes It takes them to get to school in the morning. Here is what they answered.

12, 6, 14, 15, 10, 6, 4, 10
Find the mean and median travel times for these students.
If necessary, round your answers to the nearest tenth.

Answer 1

Mean: 11.75 minutes

Median: 11 minutes

Explanation:

To find the mean travel time, we need to add up all of the travel times and then divide by the total number of students:

mean = (12 + 6 + 14 + 15 + 10 + 6 + 4 + 10) / 8 = 11.75

So the mean travel time is 11.75 minutes.

To find the median travel time, we need to arrange the travel times in order from least to greatest:

4, 6, 6, 10, 10, 12, 14, 15

Since there are an even number of travel times, the median is the average of the two middle values. In this case, the two middle values are 10 and 12:

median = (10 + 12) / 2 = 11

So the median travel time is 11 minutes.
