Complete the following steps to specify the data for the power and sample size calculation.
If you enter multiple values into a field, separate the values with a space. You can also use shorthand notation to indicate multiple values. For example, you can enter 10:40/5 to indicate sample sizes from 10 to 40 in increments of 5.
Comparison proportions: Enter one or more proportions that are meaningfully different from the Hypothesized proportion. Usually, the difference between the comparison proportion and hypothesized proportion is the smallest difference that has practical consequences for your application.
For example, a marketing analyst wants to determine whether the proportion of customers who respond to a survey differs from the national average of 4.3%. Specifically, the analyst wants to know whether the proportion differs by 1% from the national average, and enters 0.033 and 0.053.
