Graphpad quickcalcs. You want to design a study with very high power to detect very small effects and with a very strict definition of statistical significance.

CT REGISTRY APPLICATION PROCESS
StatMate shows you the tradeoffs Some programs ask how much statistical power you desire and how large an effect you are looking for and then tell you what sample size you should use.

Some can be used for data entry and data analysis, others to make more simple calculations.

All the documentation you need is built right into the program. GraphPad StatMate. This application is available only for iPhone users. Online tools for statistical calculations. Skip to content.

As with power calculations, different scientists may interpret the same results this study (given its sample size and variability) would almost certainly have.

Extremely easy to use software to determine sample sizes for laboratory and preclinical studies.

calculation of the sample size for different study designs; Report for power GraphPad StatMate calculates sample size, power and more. Three of StatMate's calculators help you properly design and set up your StatMate suggests a test, and tells you which GraphPad programs support that test. Calculate sample size - How many subjects (data points) do you need? Naturally StatMate calculates the power of a test to detect various hypothetical differences.
One benefit of larger sample size is you have more power to detect a specified effect, or with constant power can detect smaller effect sizes.
