Question

Charlotte recorded the number of minutes she spent exercising in the past ten days: 10, 12, 5, 2, 7, 1, 14, 3, 5, 6. Find the median of the data.


The median is ____ minutes.

Answer 1

First, you have to list all the numbers in order

Can you do them from least to greatest?

1, 2, .. and so on

Answer 2

the median is going to be the middle number

and since there's 10 numbers, there isn't going to be 1 number in the middle. There'll be two left over so you have to take the average of it

Answer 3

but first, let's just list out all the numbers in order from smallest to biggest

Answer 4

1,2,3,5,5,6,7,10,12,14

Answer 5

so what are the middle two numbers?

since it's 10 numbers, we're going to have two numbers in the middle
if it was 9 numbers, then we would have had only one number and that would be the median

so what are the two numbers in the middle?

Answer 6

5,6

Answer 7

Good! So now we have to take the average of that

so we add up the numbers
and since it's two numbers, we divide by 2

(5+6) / 2 =

Answer 8

5.5

Answer 9

And that's the median!
