Calculating Reach

Calculating Reach Graphic

As you tackle REACH issues, there are two important questions to ask:

1) What percent of the target population are you reaching? (Use the calculator to get some answers.)

2) Are your participants the people you need to reach? In other words, are the participants representative of your target population?

There are ways to calculate representativeness and we will post calculators when they are available. Please check back!
