SciStatForge: Stats Calculator

SciStatForge is a statistics calculator for researchers, graduate students, and paper authors who need a correct result quickly, without opening a spreadsheet.

• Descriptive stats: mean, median, mode, SD, variance, standard error, range, quartiles, IQR, and outlier detection
• One-sample t-test with t, df, exact p-value, Cohen's d, and a confidence interval
• Two-sample t-test with Welch or pooled variance and a CI for the mean difference
• Pearson correlation with r, R², a significance test, and a confidence interval for r
• Linear regression with slope, intercept, R², standard errors, confidence intervals, and a scatter plot with the fitted line
• Paired t-test and one-way ANOVA with F, exact p-value, and effect sizes (η², ω²)
• Chi-square goodness-of-fit and independence tests with Cramér's V
• Rank-based tests: Mann-Whitney U, Wilcoxon signed-rank, and Spearman correlation
• Pick the test direction — two-sided, greater, or less — at 90%, 95%, or 99% confidence, with one-sided confidence bounds
• Paste data straight from a spreadsheet column; invalid values are pointed out clearly
• Share each result card as text for a manuscript, thesis, or lab report, and revisit past tests in history

Every result shows the formula used, so you can cite it with confidence.
