Mode Mean Median and Range

In Math I am learning . . . .

Mode:Mode means the number used most often. 
1,2,2,3,6,7. =2
Mean: Add all the numbers together.Then divide by by how many numbers there are. 
1+2+2+3+6+7=21
21➗6=3.5
Median: The number in the middle.
1,2,2,3,6,7,7.=3
If there are 2 numbers in the middle,  add the numbers together, 
then divide the number by 2.
1,2,2,3,6,7, 
2+3=5
5➗2=2.5
Range:Take the largest number then takeaway the smallest number.
7-1=6
