Statlio vs Eikos

Statlio is a complete statistics lab in your pocket. For students, researchers, clinicians and marketers: enter data, run the test, follow the step-by-step solution, copy it in APA format. NO NEED TO KNOW WHICH TEST TO PICK The Test Selection Wizard guides you to the right test with 2-3 plain questions. Unsure about normality? You can check your data separately with the built-in Shapiro-Wilk test. 26 CALCULATOR MODULES • Descriptive statistics with histogram and box plot • Hypothesis tests: t-tests (one/two-sample, paired), z-test, chi-square, ANOVA • Nonparametric: Mann-Whitney U, Wilcoxon, Kruskal-Wallis • Distributions: Normal, t, Chi-square, F, Binomial, Poisson, with interactive charts • Confidence intervals, sample size, A/B testing, regression, correlation • Normality test (Shapiro-Wilk) • 6 new calculators: Fisher exact, exact binomial, McNemar, Friedman, Cohen Kappa and Cronbach Alpha. The catalog now includes 26 modules. • t-test power planning, summary-statistics analysis, Welch ANOVA and advanced multiple comparisons. • 9 distributions, including hypergeometric, exponential and uniform.
