Answer 1

How to calculate the IQR:

1) Organize your data - least to greates.
2) Find the median
3) Find the lower (Q1) and upper (Q3) half of the data
4) Q3 - Q1 = IQR

Answer 2

I'll do the first step for you (organizing). c;

Here:
100,120,130,188,196,220,265,300

Now that it is organized in ascending order, it will be easier to find the mean, then to continue on with the other steps. c:

Answer 8

Q2 = 192
Q1 = 120
Q3 = 265
I think it was just the median of those two data...like at first we had:
100 ,120, 130, 188, 196, 220, 265, 300
then we found the Q2 or median of the data and erased those 1 or 2 numbers and cut it in half:
100 ,120, 130
220, 265, 300
find the mean and u will find ur Q1 and Q3...is that about right mister @kewlgeek555
