To easily find the mode, put the numbers in order from least to greatest


Which is, 1,2,4,4,7,7,7,7,9

 Count how many times each number occurs. The number that occurs the most is the mode!

7 occurs the most! So the mode is 7.

Find the largest and smallest values in the set

They are 1 and 9.

Subtract the smallest value from the largest value to find the range

1 - 9 =  8

The range is 8.
The mode is the number in a set of numbers that you see the most...
The range is the difference between the highest and lowest number....
So for the numbers 7, 7, 7, 2, 4, 4, 7, 1, 9, 
The mode would be 7 as it's the most common number
The range would be 8 because if you subtract the lowest number from the highest (9-1) you would get 8

Hope this helps! :)
