Use free specifications and guides for packaging research data and contextual metadata. A metadata package does not itself provide hosting or scientific validation.
Combine Independent Group Means and SDs Correctly
Reconstruct one descriptive summary from non-overlapping groups without confusing combined variability with a pooled within-group SD.
Audit a Fixed-Effect Inverse-Variance Calculation
Check effect scales, standard errors, independence, and weighting before interpreting a pooled estimate.
Investigate Heterogeneity Before Explaining It
Review extraction, clinical differences, and uncertainty before turning an I-squared statistic into a conclusion.
Specify the Quantile Method Behind Your Quartiles
Explain why software can produce different quartiles and record a reproducible summary convention.
Distinguish Raw and Scaled Median Absolute Deviation
Calculate median-based spread while documenting scaling, ties, and limits of interpretation.
Estimate Review Screening Work Without Hiding Assumptions
Convert record counts, reviewer effort, and pilot timings into a transparent workload estimate.
Calculate a Fisher Interval for Pearson Correlation
Check complete-pair counts and assumptions before translating a correlation into an approximate confidence interval.
Audit the Scatterplot Behind a Correlation
Look for curvature, influential points, subgroup structure, and repeated observations before interpreting r.
Freeze an Analysis Version with a Recoverable Decision Trail
Capture the data, code, plan, environment, and outstanding decisions needed to reproduce a defined analysis release.
Review Table Shells Before Filling Them with Results
Resolve populations, denominators, units, time points, and footnotes before generating research tables.
Combined independent-group summary audit
Reconcile source group summaries with within- and between-group sums of squares.
