9 in this method a value e is calculated based on decided sample size. Some researchers do, however, support a rule of thumb when using the sample size. If a value of e is .

Define population size or number of people · designate your margin of error · determine your confidence level · predict expected variance · finalize .

9 in this method a value e is calculated based on decided sample size. · n = population size • e = . ((1.96)2 (0.5) (0.5)) / (0.05)2 = 385. The values of p1 and p2 that maximize the sample size are p1=p2=0.5.
