Editing method comparison
Seven approaches, transparent filtering and matrix export.
Seventeen working tools for comparing evidence, checking arithmetic, and building research briefs. Equations and assumptions are visible. Your inputs are processed in this browser.

Calculate pooled standard deviation, Cohen’s d, and small-sample-corrected Hedges’ g for two independent groups.
Explore an approximate per-group sample size for a two-sided, balanced comparison of two independent means.
Inspect the mean, sample standard deviation, standard error, and coefficient of variation of a numeric series.
Check a simple laboratory-reagent dilution with explicit units and a final-volume constraint.
Estimate growth over an interval using a simple exponential model and two cell-count observations.
Compare matched before-and-after values without treating the pairs as independent groups.
Document what a research record reports—and what you still need to retrieve.
Generate the next evidence questions for a selected study model and outcome.
Convert a pixel measurement using a known scale bar in the same image.
Apply the Benjamini–Hochberg step-up adjustment to a list of p-values.
Compare up to three Atlas records side by side without collapsing different models into one score.
Turn a research question into an editable, downloadable brief. All text stays in this browser unless you choose to share it.
These utilities are educational and research-planning aids. They do not diagnose disease, prescribe treatment, estimate a person’s biological age, or replace a qualified statistical or scientific review.
