Statistical analysis with publication-ready results

Upload your data, pick a test — tables and figures are prepared in one action, either for an Uzbek dissertation (OAK) or for an international journal (APA/Scopus). Computation runs in your browser.

No sign-up — one click to a real first result.

What makes it different

The analysis is the means; the export is the product

A real table, not a picture of one

Tables arrive in Word as native cells, never as an image. Figures come as vector plus a 600 dpi raster. No manual reformatting.

Two standards, one result

Table conventions for an Uzbek dissertation and for an international journal are opposite. You choose which one applies, right before export.

A p-value never travels alone

Every result carries an effect size and its confidence interval. That omission is the single most frequent reason reviewers send a paper back.

Data never leaves the browser

Computation happens entirely on your machine. Clinical or dissertation data is not uploaded to a server.

Two standards

A dissertation table and a journal table are not the same object

Put real OAK dissertation practice next to APA 7 / Scopus requirements and the rules come out opposite. There is no single correct table — the standard is chosen at export time.

Available analyses

Every test is checked against reference values

Computation is deterministic. The AI never does the maths — it may only write prose around numbers that are already computed and verified.

Descriptive

  • Descriptive statistics

    n, mean, standard deviation, median, IQR, skewness and kurtosis, 95% CI of the mean.

  • Frequency distribution

    Count, percent, valid percent and cumulative percent.

  • Shapiro-Wilk test

    With a Q-Q plot and histogram. Descriptive only — it never branches the analysis.

Parametric

  • t-test (independent samples)

    Welch by default, with fractional degrees of freedom; Hedges' g and its 95% CI.

  • t-test (paired samples)

    t, df, p; the CI of the mean difference and Hedges' g.

  • One-way analysis of variance

    F, df, p; partial η² with a 90% CI; Tukey or Games-Howell comparisons.

  • Factorial analysis of variance

    Main effects and their interaction; F, df, p; partial η² with a 90% CI.

  • Analysis of covariance (ANCOVA)

    Covariate-adjusted means; F, df, p; partial η² with a 90% CI.

  • Repeated-measures analysis of variance

    Mauchly sphericity test, ε̂ and a Greenhouse-Geisser or Huynh-Feldt correction; fractional df.

Nonparametric

  • Mann-Whitney U test

    U, Z, p; rank-biserial correlation; median with both IQR bounds.

  • Wilcoxon signed-rank test

    The rank-based counterpart for paired samples: T, Z, p and an effect size.

  • Kruskal-Wallis test

    H, df, p; the ε² effect size; Dunn comparisons.

  • Correlation analysis

    Pearson, Spearman or Kendall's τ_b; a confidence interval always, significant or not.

  • Friedman test

    A nonparametric test for repeated measures; χ², df, p and Kendall W.

  • Correlation matrix

    Pairwise correlations across several variables; n and a CI for every cell.

Categorical

  • Pearson's χ² test

    2×2 and r×c tables; φ or Cramér's V; expected counts shown.

Regression

  • Linear regression

    Per predictor B, SE, β, t, p and its CI; R², F, VIF and the condition number.

  • Logistic regression

    Per predictor B, SE, Wald, p; OR with a 95% CI; model χ² and pseudo-R².

Reliability

  • Reliability analysis

    Cronbach's α and McDonald's ω with confidence intervals; no “acceptable” threshold is imposed.

Accuracy

Grounds for trusting the number that goes into your dissertation

The Filip dataset is a 10th-degree polynomial over 82 observations at a condition number of 1.78·10¹⁵. Several commercial packages have historically returned zero correct digits on it. We use a QR decomposition rather than the normal equations, and we publish the achieved figure for every dataset.

Questions

Frequently asked questions

Does this replace SPSS or JASP?

For these tasks, yes. The analyses are computed with effect sizes and confidence intervals, and the result comes out directly as a journal-ready table and figure. Factor analysis, survival analysis and panel econometrics are not included yet.

Does OAK require statistical analysis?

No statute says so. But since the impact-factor and Hirsch-index requirements took effect on 1 January 2020, OAK-listed and international journals expect statistical grounding in practice — the results chapter is 50-60% of a dissertation.

Where is my data stored?

Computation runs in your browser and the file is never uploaded. When you close the page the data stays on your device.

How can I be sure the result is accurate?

Our achieved figures on the certified NIST StRD datasets and the reference-library versions are published openly. Every analysis is checked against R and SciPy values.

Which files can I upload?

CSV, TSV and Excel (.xlsx). SPSS (.sav) and Stata (.dta) are not supported yet — export CSV from those programs instead.

Does an AI write the results?

No. Every number is computed by deterministic algorithms. Prose is only ever formed around numbers that are already computed and verified, and it never makes a causal claim.
