Analyses

Every analysis in Quanta

The complete list, one procedure per line, so you can check whether Quanta covers your study before you download it. Everything here runs natively on your Mac and reports in APA 7. At the bottom: what Quanta does not do yet, stated just as plainly.

Descriptives & Explore
Descriptive statistics (mean, SD, median, quartiles, skewness, kurtosis, standard errors) · frequencies and demographic tables · cross-tabulations · normality tests (Shapiro-Wilk, Lilliefors) · stem-and-leaf displays.
Compare Means
One-sample t test · independent-samples t test (Student and Welch) · paired-samples t test · one-way ANOVA with post-hoc pairwise comparisons (Tukey HSD) · factorial ANOVA · ANCOVA · repeated-measures ANOVA with Mauchly's test and Greenhouse-Geisser and Huynh-Feldt corrections · effect sizes (Cohen's d, Hedges' g, eta squared, partial eta squared) throughout.
Nonparametric
Mann-Whitney U · Wilcoxon signed-rank · Kruskal-Wallis · Friedman.
Categorical
Chi-square test of independence · chi-square goodness of fit · Fisher exact test · McNemar test · Cramer's V.
Correlation
Pearson · Spearman · Kendall · partial correlation · APA-formatted correlation matrix.
Regression
Multiple linear regression (OLS) with diagnostics · logistic regression with separation warnings · ordinal (proportional-odds) regression · Poisson regression.
Scale & Reliability
Cronbach's alpha · McDonald's omega · item-total statistics · alpha-if-item-deleted · reverse coding · automatic scale-item detection.
Data Reduction
Principal components analysis · exploratory factor analysis with varimax rotation · cluster analysis (k-means and hierarchical).
Multivariate
MANOVA · discriminant analysis · canonical correlation.
SEM & CFA
Confirmatory factor analysis · structural equation models written in reproducible model syntax with a live path diagram · mediation models as SEM path models (x → m → y templates built in).
Bayes factors
JZS Bayes factors for t tests · one-way ANOVA Bayes factors (Rouder's method) · correlation Bayes factors · g-prior Bayes factors for regression · a clearly labeled BIC-approximate Bayes factor for SEM · evidence labels that quantify support for the null as well as against it.
Complex Survey Design
Design-weighted means, totals, and proportions · sampling weights, strata, and clusters · Taylor-linearized standard errors · design degrees of freedom · design effects (deff) · naive-weighting warnings.
Missing Data
Missing-data diagnostics · Little's MCAR test · multiple imputation by chained equations (MICE) with Rubin-pooled estimates.
Not in Quanta yet

Stated plainly

Quanta does not yet include multilevel (hierarchical linear) models, survival analysis, or full Bayesian estimation; Bayesian support today means Bayes factors for the models listed above. If your study needs one of these, Quanta is not the right tool for that analysis yet, and this page will change when that changes.

Validation

Checked, not assumed

The engine is validated against NIST certified reference datasets and published statistical standards, with the per-method record public on the validation page.

Reporting

Every result, APA 7 ready

Any analysis on this page can be added to an editable APA report: correct table formatting, notes, and symbols, exported to PDF, Word, RTF, or Markdown.

Something missing?

Ask before you commit

If your required procedure is not listed, check the guide or ask a human statistician at Stats Assistance whether Quanta fits your study.
