Question

What’s the median of 1,2,3,4,5,6,7,8,9 and 10

Answer 1

5.5

Explanation:

The median is the number in the middle of a data set.

First, lets arrange the numbers from least to greatest:

1,2,3,4,5,6,7,8,9,10

Now, cross one number off each end of the data set until we reach the middle.

1,2,3,4,5,6,7,8,910

2,3,4,5,6,7,8,9

3,4,5,6,7,8

4,5,6,7

5,6

There isn’t one number in the middle, there is 2 numbers(5 and 6). Therefore, we need to average the numbers.

Add the numbers, then divide by 2. We divide by 2, because there are 2 numbers.

Add: 5+6=11

Divide by 2: 11/2=5.5

Therefore, the median is 5.5

Answer 2

5.5

Explanation:

Median = middle number of number set

Arrange from least to greatest:

1 2 3 4 5 6 7 8 9 10

Middle numbers: 5 and 6

Find avergae of 5 and 6: (5+6)/2 = 5.5

Thus, median = 5.5
