P5.7—Evaluation of investigations

Evaluation asks whether anomalies, range, intervals, measurement method, controls and replication allow a confident answer.

Propose changes that directly reduce the identified limitation and explain how confidence would improve.

If the range stops before a plateau, extend it; if intervals are too wide, add intermediate values; if measurement is subjective, use a calibrated method.

Listing every possible limitation weakens an evaluation; prioritise the limitations that affect the conclusion.
