Assumptions
Results update as you type. Example figures are illustrative.
Your working data
Edit cells directly or import a CSV. Download “Input CSV” for the required column names. Up to 200 rows; scroll the table sideways for additional fields.
Detailed analysis
Exports include all results, regardless of the search filter. The HTML report includes assumptions and source data; use your browser’s Print command for PDF.
Chart shows the first 20 rows; negative values use a warm color. Click table headers to sort.
Compare up to four scenarios
Capture the current inputs, change assumptions and capture again. Scenarios are included in downloaded projects.
What this model includes
Difference is B minus A. Limits are mean difference ± chosen multiplier × sample SD; no confidence intervals, trend adjustment or medical interpretation.
Import and save safely
CSV imports use your current assumptions. Project files restore assumptions, rows and saved scenarios. No automatic saving: download a project before closing this page. Imports are limited to 10 MiB and 200 rows. Calculations run in your browser; the site’s advertising and analytics follow its privacy policy.
Using Paired Measurement Agreement Analyzer
Inspect differences between two measurement methods with bias, sample standard deviation and descriptive agreement limits.
- Set SD multiplier.
- Add one row for each pair in the table.
- Read the agreement chart beside your table, then download the result.
Example
The worked example includes P1, P2, P3, P4. Change the first sd multiplier setting and compare the result with a saved baseline.
Questions & answers
What does Paired Measurement Agreement Analyzer calculate?
Inspect differences between two measurement methods with bias, sample standard deviation and descriptive agreement limits.
What are the important limitations?
Difference is B minus A. Limits are mean difference ± chosen multiplier × sample SD; no confidence intervals, trend adjustment or medical interpretation.
Can I continue my work later?
Yes. Save a project JSON file and reopen it with Import CSV / project. It contains the working data, assumptions and up to four scenarios. Nothing is saved automatically.
What CSV columns do I need?
pair, a, b. Download Input CSV for a compatible example. CSV imports keep your current assumptions.
Are these example figures current industry benchmarks?
No. They are illustrative values to demonstrate the model. Replace them with figures appropriate to your situation.
