Maths that I learnt

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 take away the smallest number.
