**Sample Size Calculator calculates power & sample size**

This can be done using an online sample size calculator or with paper and pencil. Your confidence level corresponds to a Z-score. This is a constant value needed for this equation.... The program outputs the sample sizes required to estimate the true value with the desired precision and confidence, for both an infinite population and for a population of the specified size. If population size is left blank or zero, only the sample size for an infinite population is calculated.

- Continuous outcome superiority trial. This calculator is designed for continuous outcomes (such as walking distance, blood pressure, white blood cell count) in parallel group superiority trials.
- Defining your population will help you estimate the population size. For example, if you are studying a single flock of ducks, then your population would consist of all the ducks in that flock.
- Deciding how many items to sample is a complicated matter that involves multiple calculations. However, software like IBM's SPSS can help you calculate sample sizes in a snap. However, software like IBM's SPSS can help you calculate sample sizes in a snap.
