sample method - systematic
the sample is agreed upon using a specific rule when out in the field. The data is evenly distributed and is ensures good coverage of the area. However, it may be bias and may not be representative.
Sample method - Stratified
A sample frame made up of sub-sets is used to choose the sites it needs to be representative and proportional to the total area. You have to conduct research and bias is introduced.
EQI (Environmental quality index)
Use opposite adjectives or opposite descriptors to assess the quality of the environment. These opposite statements can be used to capture the viewpoints of the students themselves or the member of the public.
limitations of EQI
- subjective - less accurate
- scale - when in the middle is useless
