Answer 1

Okay what is the median?

Answer 2

To find the Median, place the numbers you are given in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. Put them in order: {10, 11, 13, 15, 16, 23, 26} The middle number is 15, so the median is 15. (If there are two middle numbers, you average them.)

Answer 3

Use the lines on the box to help you. The left line is the 1st quartile, the middle line is the 2nd/median and the right line is the 3rd quartile. So anything right of that right line is 25% of the data. Anything left of the left line is also 25% of data.

Answer 16

So its 4

Answer 17

I said 4 at first

Answer 18

so is it 4?

Answer 19

the easiest way is to see that a score of 6 is lining up with the third/upper quartile. Therefore anything 6 or above must represent the upper 25% of data.
So 25% of 12 schools is 3 schools.
