A full analysis suite, native to your Mac
The methods social, behavioral, and health researchers actually use, grouped by what you are trying to do, with the setup on the right and results in the center.
What Quanta does
Descriptives & Explore
Means, distributions, frequencies, cross-tabs, normality (Shapiro-Wilk, Lilliefors), stem-and-leaf, demographic tables.Compare Means
One-sample / Welch / Student / paired t-tests, one-way and factorial ANOVA, ANCOVA, and within-subjects repeated-measures ANOVA with sphericity corrections.Bayesian, side by side
Frequentist and Bayesian results together: JZS Bayes factors for t-tests, Bayes factors for correlation and regression, one-way ANOVA (Rouder's method), and a clearly labeled BIC-approximate Bayes factor for SEM. Quantify evidence for the null, not just against it. Validated against published reference results.Correlation
Pearson, Spearman, Kendall, and partial correlation, plus an APA correlation matrix.Regression
Linear (OLS), logistic, Poisson, and ordinal (proportional-odds) regression with effect sizes and diagnostics.Scale & Reliability
Cronbach's alpha and McDonald's omega, item-total statistics, alpha-if-deleted, reverse coding, and automatic scale-item detection.Data Reduction
Principal components, exploratory factor analysis (with varimax), and cluster analysis (k-means, hierarchical).Nonparametric & Categorical
Mann-Whitney, Wilcoxon, Kruskal-Wallis, Friedman, chi-square, Fisher exact, and McNemar.Multivariate
MANOVA, discriminant analysis, and canonical correlation.SEM & CFA
Structural equation modeling and confirmatory factor analysis with a live path diagram, written in reproducible model syntax.Survey Weights
Design-based estimates with strata and clusters (Taylor-linearized standard errors, design df, deff).Data Quality
Missing-data diagnostics and Little's MCAR, multiple imputation (MICE, Rubin-pooled), out-of-range and duplicate checks.See the complete analysis list, one procedure per line →
How the pieces fit
Bring data in from anywhere
CSV, TSV, Excel, SPSS (.sav), and Stata (.dta) files, plus ReliCheck and MM Studio survey packages. Variable types are detected on import.
From result to manuscript
Add any result to an editable APA report. Tables follow APA 7 (leading-zero rule, spanners, italic symbols, notes). Export to PDF, Word, RTF, or Markdown.
Plain-language explanations, on-device
Every result can be explained in plain language by an on-device model, private, no upload. It explains your validated numbers; it never computes them.
Guardrails built in
Separation warnings, small-sample cautions, and naive-weighting flags that generic statistics tools do not give you by default.
