First step is to put the data in order from least to greatest.

• true

• false

Why do you think he is crossing the numbers off in the original problem?

• just for fun

• to add more work to what he has to do

• to make sure he doesn't miss any numbers

What do you think you would do next to find the RANGE - "the difference between the highest and lowest values in the set?"

• add them all together

• add the highest and the lowest numbers

• subtract the highest and lowest numbers

• figure out which number occurs most often

• find the middle number

What is the RANGE for # 1?

• 12

• 10

• 8

• 2

First you must....

• add them up to find the range.

• Put them in order from least to greatest to find the range.

How do you calculate the range?

• find the middle number

• find the number that occurs most often

• add them all up and divide by how many numbers in the data set

• add the highest number and the lowest number

• subtract the highest number and the lowest number

The range is ....

• 22

• 23

Why does it help to put the numbers in order from least to greatest before finding the RANGE?

• it is fun!

• if your numbers are organized, you are less likely to make a mistake when finding the highest and lowest number

• to make it harder  :-(
