6P.13—Unit 6 implementation and measurements

Syllabus
2021
Objective
6
Level
A2

Implement measurements consistently so variation can be interpreted

During implementation, follow the same sequence for every treatment, record raw readings with units and note deviations. Randomise or balance order when drift could bias one condition.

Measure each sample at the same time interval and temperature; if a reading is delayed, record that deviation instead of silently treating it as equivalent.

A neat table cannot remove procedural bias.
