How to use Power & Study Design

Sample-size and power calculations for means, proportions, correlations and ANOVA, with a design wizard that suggests the right test for your question.

Before you start

• • A signed-in SciExpert account

Steps

1. 1

   Open Power & Study Design

   From the workspace sidebar choose Power & Study Design. On a phone, open the All menu and tap Power & Study Design.

2. 2

   Set up your inputs

   Sample-size and power calculations for means, proportions, correlations and ANOVA, with a design wizard that suggests the right test for your question. Start with the smallest realistic input so you can check the output before scaling up.

3. 3

   Run it

   Run the tool and check the first output: power and sample size for the common designs.

4. 4

   Review what came back

   Work through the results: effect size, alpha and attrition handled explicitly; study-design wizard for choosing a test; text you can paste into a protocol or proposal.

5. 5

   Save or export

   Save the configuration as a preset if you will repeat it, and export the output when you need it outside SciExpert. Your inputs persist across refreshes and sign-ins.

Tips

• • Start with a small input, verify the output, then scale up.
• • Save a preset once the configuration works so you can reuse it across papers.
