Beoga vs StatsCalc Usage & Stats

Short Description: Computes descriptive statistics of quantitative variables. Performs statistical tests and computes confidence intervals in one, two and multiple-sample situations. Provides regression analysis using linear, exponential and power-law models. Computes probabilities and quantiles for standard statistical distributions. Provides statistics features usually found on hand-held calculators. Accuracy of numerical results tested against Wolfram Mathematica. Features: Data Entry: Easy (list-based) entry of quantitative and categorical data, and two-way tables. Voice-based data entry (Siri) is possible. One-Sample Methods: Z-Test for the Mean. Z-Interval for the Mean. T-Test for the Mean. T-Interval for the Mean. Wilcoxon Signed Rank Test. Chi-squared Test for the Standard Deviation. Chi-squared Interval for the Standard Deviation.
