I am curious to get some feedback regarding determining sample sizes for test marketing purposes.
I want to determine how many people I need to test an email on to guage the results of how the total population would respond to the test market email.  If I know my population size is say 20,000, I can tolerate a 3% margin or error, I get a consistent email open rate of 25% and I want to be 80% confident that the test results match the population.
Is there a specific formula I need for this becuase I’m getting confused as to which one it would be and if the information I have would fit into that formula.

Yes there is a formula:
n = (z/delta)squared times p(1-p)  Substitute your .03 for delta, your .25 for p and find the z value for a confidence level of 80% and substitute for z.

Tex,
Good call…… good website!
It bothers me that 19 people want someone to send them an “Excel Template” that is a simple input of the formula posted by Darth.  It’s a simple spreadsheet design most Excel users can set up in two minutes or less……
But the website you posted makes it even better…. with alternate scenarios……
Bookmarked here…. thanks!
