Range is a word that you guys can use in your real world vocabulary. This is a word that you actually use in your real life. Find the range of student age in a statistics class. Remember range means highest number subtract the lowest number, so it doesn’t matter that these are all in jumbled order like they are not going from smallest to biggest. All I need to do is scan and find the largest number and find the smallest number and subtract them.

So let’s see my highest number is going to be 25, my lowest number is 14 there and then the range Is highest subtract lowest, 25 take away 14 is 11. That’s my range I would say there is an 11 year range in the ages of students in this statistics class. That’s a pretty good range. If you guys were the 14 year old sited in that classroom, sitting next to a 25 year old you might feel like the range was pretty damn big, especially if it’s 11 years.

So officially to write this correctly I should say my range is 11 years to use the label and reconnect it back to the real world context.
