Question

The 6 students in Mrs. Butler's class were asked how many minutes it takes them to get to school in the morning. Here is what they answered:5, 8, 13,5, 3,3Find the mean and median travel times for these students.If necessary, round your answers to the nearest tenth.

Answer 1

Mean

Add all numbers then divide by total numbers.

Total students = 6

$\operatorname{mean}=\frac{5+8+13+5+3+3}{6}=\frac{37}{6}=6.166$

Round to the nearest tenth = 6.2

Answer: mean = 6.2

Median

List your numbers from smallest to largest and chose the number in the middle.

This is: 3, 3, 5, 5, 8, 13

The middle are 5 and 5, therefore:

$\frac{5+5}{2}=\frac{10}{2}=5$

Answer: median = 5
