P3.7—Interpreting data and observations

Interpret trends, compare groups, identify anomalies and judge confidence using the spread and design of the data.

Use graphs to estimate unknowns only within a defensible range and link the pattern to a biological mechanism.

A single point far from a smooth trend may be an anomalous reading, but it should be checked against the method before deletion.

A visible trend is not automatically statistically or biologically meaningful.
