With 11 calculators, statmagic PRO covers the most common topics in intro stat classes, each with individual help pages and specific example problems. These 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 (allows 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 (for a mean or a proportion).
> Least-squares linear regression (with an automatic scatterplot that colors outliers, and the option to use the equation to predict y for any chosen x).
> Chi-squared (calculates, and can switch between, the observed, expected, and squared values instantaneously; handles up to a 7x7 table).
