What is the mode ?

• The middle number when numbers are put in order

• The number that occurs most often (most number of times)

• The average - found by adding all numbers together and dividing by how many numbers total.

• The maximum minus the minimum number

What is the median ?

• The middle number when numbers are put in order

• The number that occurs most often (most number of times)

• The average - found by adding all numbers together and dividing by how many numbers total.

• The maximum minus the minimum number

What is the range ?

• The middle number when numbers are put in order

• The number that occurs most often (most number of times)

• The average - found by adding all numbers together and dividing by how many numbers total.

• The maximum minus the minimum number

What is the mean ?

• The middle number when numbers are put in order

• The number that occurs most often (most number of times)

• The average - found by adding all numbers together and dividing by how many numbers total.

• The maximum minus the minimum number
