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.
