Environmental baseline anomaly calculator

Calculate absolute anomaly and baseline sample-standardized anomaly with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use absolute anomaly and baseline sample-standardized anomaly to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Absolute anomaly

Anomaly=x-baseline mean; standardized by sample SD.

Baseline sample-standardized anomaly

Anomaly=x-baseline mean; standardized by sample SD.

Baseline mean

Anomaly=x-baseline mean; standardized by sample SD.

Assumptions & limits

Assumptions & limits

  • Calculation uses the entered values and stated mathematical model; quantities must use the labelled units. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Anomaly=x-baseline mean; standardized by sample SD.
