Sampling Location Strategy
The method used to determine where samples are collected within a study area to ensure representative and unbiased data.
Real World
Scientists studying pollution in the River Thames use stratified random sampling — dividing the river into zones (urban, suburban, rural) then randomly placing quadrats within each — to ensure all habitat types are represented fairly.
Exam Focus
For 'justify your sampling strategy' questions, explicitly state why your chosen method reduces bias and suits the specific environmental variable being measured.
