Sample Sizes

Use this field to list the values for total sample size for which to compute the appropriate power.

Values must be positive integers and can be specified in any of the following forms:

•	a single value,

•	a range of values, typed as 100 to 800, for example (with a default increment of 50), or

•	a range of values with a specified increment, typed as 100 to 800 by 10, for example.

To Specify Sample Sizes:

Left-click in the text field and type the desired values.

For example, to specify a range of values from 800 to 1200 in increments of 20, type 800 to 1200 by 20 in the text field, as shown below:

Note: This field can be left blank if values are specified in the Power Values field.
