Question
The 5 students in Mrs. Clark's class were asked how many minutes it takes them to get to school in the morning. Here is what they answered.3, 15, 5, 14, 14Find the mean and median travel times for these students.If necessary, round your answers to the nearest tenth.
Solution
To find the mean (average) travel time, you add up all the times and then divide by the number of times.
Here's how you do it:
- Add up the times: 3 + 15 + 5 + 14 + 14 = 51 minutes
- Divide by the number of times: 51 ÷ 5 = 10.2 minutes
So, the mean travel time is 10.2 minutes.
To find the median (middle) travel time, you arrange the times in numerical order and then find the middle number.
Here's how you do it:
- Arrange the times in numerical order: 3, 5, 14, 14, 15
- Find the middle number. Since there are 5 numbers, the middle number is the third one, which is 14.
So, the median travel time is 14 minutes.
