Statmagic’s calculators cover all of the most common topics of intro stat classes. Each comes with its own help page and memorable example problems. The calculators are: • Descriptive stats (mean, quartiles, standard deviation, etc.). • Probabilities (with Z and T scores) on the normal distribution. • One- and two-sample tests of mean (Z, T, and Welch tests). • One- and two-sample tests of proportion (allowing both decimal “0.48” and fractional “54/112” type entries for p). • Confidence intervals (for a mean or a proportion, featuring a full, auto-filling CI formula, so you can see how the CI is constructed). • Minimum N of a sample (for measuring a true mean or a proportion within a set margin of error). • Least-squares linear regression (with an automatic scatterplot coloring outliers, and a tool to calculate the predicted y for any chosen x using the regression equation — plus, this y-hat is automatically plotted on the line, turning orange to warn you of extrapolation!). • The best-designed Chi-squared calculator out there. (Which, besides furnishing full test results, including the critical Chi-square and p values, instantly calculates cellular and total expected and Chi-squared values once you enter the observed counts. Handles up to a 7×7 table!)
Learn statistics efficiently, and finish your stats homework faster. Learn, practice, and master stats with Statmagic PRO!
Statmagic PRO helps you finish your stat homework faster. Its easy-to-use calculators eliminate tedious number-crunching, and help you avoid common mistakes — all while making stats simpler, clearer, and easier to learn.
It also contains no ads or in-app purchases. Meaning no interruptions and no paywalls keeping you from full functionality!
Statmagic PRO is the best, easiest-to-use app for learning stats. Why? • Simplicity. Statmagic uses a simple and familiar calculator layout. • Press-and-hold definitions. Every input field has an on-the-spot definition, so you can quickly remind yourself what each statistical symbol means, and enter the right value for it. • Error checking. Statmagic automatically checks for typos and anomalous numbers, and helps you prevent simple mistakes. For example, if you select a Z test when n is < 30 and the standard deviation is not known, Statmagic will politely suggest a T test instead. • Complete and accurate results. Statmagic PRO’s 11+ calculators have been tested exhaustively to ensure that they return correct answers, first and foremost. • Automatic graphics and plots. So you can visualize what’s going on. For example, you can finally skip the confusing Z table — Statmagic automatically graphs the area under the curve, for any Z or T score! • User-specified answer rounding. Statmagic will round its answers to any number of digits that you specify.
