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 rates: Enter one or more rates that are meaningfully different from the Hypothesized rate. Usually, the difference between the comparison rate and hypothesized rate is the smallest difference that has practical consequences for your application.
For example, an analyst enters 43 and 53 to determine whether the number of transactions per hour differs from the hypothesized rate of 48 by at least 5.
