Hypothesis Tests

AutoTest

Analyze the data and automatically run the test for variance and mean/median. This greatly reduces the time required to find and run the correct Hypothesis Test.

Advisor Wizard

The Advisor Wizard will ask you questions about your data and advise you on the correct test to perform.

Tests for variance

Analyze dataset variance using F-test, Bartlett's test or Levene's test. Quantum XL will display test statistics, p Value, 95% Bonferroni CI for StDevs, and dataset statistics.

Tests for mean

Analyze the dataset mean using One-sample t-test, Two-sample t-test, Paired t-test, One-way ANOVA, or Two-way ANOVA nested or crossed.

Tests for median (analyze dataset median)

Analyze dataset median using 1-sample Wilcoxon test, 1-sample sign test, Mann-Whitney test, Friedman test, Kruskal-Wallis test or Mood's Median test.

Quantum XL will display test statistics, confidence interval for the median, dataset statistics, and p Value.

Attribute tests

Analyze qualitative data using the One proportion test, Two proportion test, or Chi-Squared test.

Test for normality

Test your dataset for normality.

Choose between Anderson–Darling, Shapiro–Wilk, or Kolmogorov–Smirnov test methods. Quantum XL will display the test statistic, p Value, and probability plot.

Power and sample size analysis

Compute the statistical power of the test for a given sample size or calculate the required sample size.

Power and sample size analysis are calculated differently for different hypothesis tests.

Quantum XL supports power and sample size analysis for One sample t-test, Two sample t-test, Paired t-test, One-way ANOVA, One proportion test, Two proportions test, and Two variances test.
