Standardisation in Research
The process of keeping conditions and procedures consistent across all observations to ensure reliable and comparable data.
Real World
The UK Air Quality Network uses identical Defra-approved equipment and calibration protocols at all monitoring stations so that NO₂ readings in London can be directly compared with those in rural Yorkshire.
Exam Focus
For 'explain' questions on reliability, name the specific variable being controlled — vague answers like 'keeping things the same' rarely earn full marks.
