Question

3. What is the Median Average of Shoe Sizes from the data set below?

6.5, 7, 9, 9, 10, 7.5, 13, 11, 12.5, 13, 13​

Answer 1

10

Explanation:

Hi!

We first need to order the numbers in the sequence in ascending order:

`6.5,\:7,\:7.5,\:9,\:9,\:10,\:11,\:12.5,\:13,\:13,\:13`

The median is the middlemost number(s) in a sequence.

In that case, we can see that
`\boxed{\boxed{10}}` is the median.

More info:

Since there are 11 terms, we will divide by two. 11 ÷ 2 = 5.5. Since we round up from 5, we will count over 6 terms.

In doing so, we can see that 10 will remain our answer.

Hope this helps!
