Answer:
Range : 8
Mode : 1
MAD : N/A
Median : 3
IQR : N/A
Mean : 4
Explanation:
Finding Range:
To find range within a set of numbers, you have to find the smallest number, which in this case is 1. And the biggest number, being 9. Then subtract the biggest number by the smallest.
9 - 1
8 is our range.
Finding Mode:
Finding Mode is finding the most common (or repeated) number within the set.
1 , 1 , 3 , 6 , 9
One appears two times unlike all the other numbers appearing once, therefore having 1 as our mode.
Finding MAD :
I have never heard of this term so I wouldn't want to cheat or give you a wrong answer.
Finding Median :
Median is simply finding the number in the middle of the number set.
1 , 1 , 3 , 6 , 9
3 is in the middle of the set, making 3 our median.
Finding IQR :
Like MAD, I have never heard of this term so I wouldn't want to cheat or give you a wrong answer.
Finding Mean :
Mean is adding all the numbers together, then dividing that final value by the amount of numbers there are.
1 + 1 + 3 + 6 + 9
20
There are five numbers within the set.
20 / 5
4
4 is our mean.
