Key Differentiators
Not just statistics — research-grade results
✅

Assumption Checking First

Before running any test, Ravens automatically checks all relevant assumptions — normality, homogeneity of variance, independence — with pass/fail indicators.

"Your data violates normality (Shapiro-Wilk p = .002). We recommend Mann-Whitney U instead of independent t-test. Run recommended test?"
📝

APA 7th Edition Output

Every result is formatted exactly as it should appear in a peer-reviewed journal or thesis chapter.

"An independent samples t-test revealed a statistically significant difference between Group A (M = 4.52, SD = 1.23) and Group B (M = 3.18, SD = 1.45), t(98) = 5.01, p < .001, d = 0.99."
💬

Plain-English Interpretation

Below every APA result, a clear interpretation any non-statistician can understand — what it means, whether it's significant, and practical effect size.

"Group A scored significantly higher than Group B, with a large effect size. This difference is very unlikely to be due to chance (less than 0.1% probability)."

Thesis-Ready PDF Export

One-click export with formatted tables, charts, APA citations, assumption check results, and interpretation — formatted exactly as a thesis chapter.

Includes: Method section text, Results table, assumption check summary, effect size, post-hoc tests, and interpretation paragraph.
🎛️

Smart Variable Selection

After upload, assign dependent, independent, grouping, and covariate roles. Ravens suggests appropriate variable types based on your data.

Detects numeric vs categorical columns automatically. Warns when a variable type doesn't match the test requirements.
