You are attending the Susan G Komen Race for the Cure and have been charged with estimating the attendance. Describe and justify two possible methods for estimating.

I can give you one method: you'll have to find what to call it.

1) take the attendance of the last five years; add all numbers and divide by 5 to give you the average attendance.

Just thought of this:

2) again look at last 5 years; see if you can get a percentage of increase for each year.

Did it increase 5% or more each year? Then take the % from just the previous year (2014) & give that to the 2015 race to project for 2016 race.
