• Easy to use interface helps you enter the pertinent information without being a statistics expert.
• Know how many observations you'll need to measure what you want.
• Know how good a measurement you'll get for any number of observations you set.
• Visualizations
• Play with sliders for key parameters and see how they affect the measurement
• Supports measurements of rates and proportions (binomial distributions) in addition to continuous distributions
• Chooses appropriate statistical test for you based on your experimental parameters. (Tests include t, z, chi square, and exact binomial).
• Set your preferred risk of both false positives and false negatives (type I error and type II error)
