Equation To Find Sample Size. Dummies has always stood for taking on complex concepts and making them easy to understand. Find the sample size for some finite and infinite population when the percentage of 4300 population is given as 005.
If you chose a different confidence level use our Z-score table to find your score. Here is an example of how the math works assuming you chose a 90 confidence level 6 standard deviation and a margin of error confidence interval of - 4. To calculate sample sizes.
Therefore the sample size can be calculated using the formula as 10000 196 2 05 1-05 005 2 10000 1 196 2 05 1-05 005 2 Therefore 370 customers will be adequate for deriving meaningful inference.
Wondering how to calculate sample size. In calculating the sample size we are interested in calculating the population. If you chose a different confidence level use our Z-score table to find your score. N 1645 2 05 1 -.
