Answer 1

Measures of variation:  ways to describe measures of central tendency for a data.

the most common measure of variation is range, so in this case, the smallest number is 1, and the largest is 17. This means the range is 16.

Interquartile Range:

Lower q: {1, 2, 4}
Upper q: {8, 12, 17}
Here you have to subtract 12 from 2, which gives you 10.

Mean absolute deviation:
Alright, let's first find the mean...

(1+2+4+5+8+12+17)
---------------------------= 7
                7

What is the distance of each number from 7?

1: 6 units
2: 5 units
4: 3 units
5: 2 units
8: 1 unit
12: 5 units
17: 10 units

After adding all of these together, and dividing by 7, you will get...

4.571428 ≈ 4.6 or 5.
