Can Prism perform sample size and power calculations?
Yes! Power analysis and sample size calculations are now available through Prism Cloud. The functionality provided there allows you to calculate required sample sizes based on predicted effect sizes or to determine detectable effect sizes provided existing sample limitations. These tools provide fully adjustable parameters for power and sample size calculations for a variety of different analytical designs, and provide guidance at every step with detailed explanations of the different choices and options.
Understanding statistical power is essential for properly conducting experiments and interpreting analytical results, and Prism Cloud's power analysis calculator helps to design adequately powered studies. Rather than simply answering the question "how many subjects do I need?", these tools present results in tabular and graphical formats, showing the tradeoffs betwen sample size, power, and detectable effect size.
Prism Cloud's power analysis and sample size calculators help you optimize your experimental designs by:
- Tailoring sample sizes to specific study requirements
- Ensuring experiments are sufficiently powered to detect predicted (or target) effect sizes
- Conserving valuable resources while maintaining statistical reliability
