Kostenloser KI-Statistik-Löser

Statistik ist ein Pflichtfach für fast jeden Hochschulstudiengang. Unser kostenloser KI-Statistik-Löser behandelt das gesamte Spektrum einführender und mittlerer Statistikprobleme.

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.
