Answer 1

I did a few, to show you how.
Slide 1:
A) class A; range of 7
B) class a; 5.5
C) class b; 6.7 appx
D) class a

These are how to find each one:

Mean: add all the numbers and divide by the number of numbers. Ex. 1+2+3= 6/3=2
Median: middle of the numbers
Range: take the smallest value away from the largest value
IQR: find the median; find the range of the numbers above and below the median. Take the range of those two numbers that is the IQR
MAD: find the mean; take absolute value of numbers and subtract mean (|x|-mean); find sum of absolute value and difference; divide by the number of numbers.
