Hi.. have a question as I'm a newbie at this and I will be asked WHY
I have a program with 3541 samples.. with error rate of 10% and accuracy of 5% and Zscore of 1.96 I get a sample size of 136.
Now I've been asked to do one with 9700 samples, same parameters and I get a sample size of 133?
I'm not soo good with Stats, I can understand why it would be the same as the calc is not linear.. but my colleages will definately want to understand how a lot of twice the size means we need to do the same # of samples.
Thanks!
