Descriptive Statistics
The solver computes mean, median, mode, range, variance, standard deviation, interquartile range, and percentiles from raw data sets. It constructs frequency distributions, identifies outliers, and describes the shape of distributions.
Probability
Probability problems are solved using classical, empirical, and subjective approaches. The solver handles simple and compound events, conditional probability, Bayes' theorem, and counting methods including permutations and combinations.
Hypothesis Testing
The AI walks through the complete hypothesis testing procedure: stating null and alternative hypotheses, selecting the significance level, choosing the appropriate test statistic, computing the test statistic, finding the p-value, and making a decision.
Regression and Correlation
Linear regression problems are solved with calculation of the least-squares regression line, correlation coefficient, coefficient of determination, and residual analysis.
ANOVA
One-way ANOVA problems are solved with complete construction of the ANOVA table including sum of squares, degrees of freedom, mean squares, F statistic, and p-value.
