what is random sampling
randomly choosing sites to collect data
random sampling advantages
- not bias - each site has an equal chance of being picked
- can easily be done with a large area
random sampling disadvantages
- sites can get clustered together meaning data collection isn’t representative
- may lead to sites that are inaccessible
what is systematic sampling
picking sites every __m
systematic sampling advantages
- gives good representation of an area
- easier to do than random sampling
systematic sampling definition
- can be time consuming
- can be bias as not all sites have an equal chance of being selected
- may lead to sites that are inaccessible
stratified sampling definition
picking sites by topic
stratified sampling advantages
- flexible - fits with a lot of different enquiries
- gives good comparison of different areas (eg. upper, middle, and lower course)
stratified sampling disadvantages
- not suitable for something like a questionnaire
- could lead to bias from person picking sites
advantages of river data
data is easy to compare downstream
disadvantages of river data
current can make collection inaccurate
advantages of pebble data
see impacts of erosion
disadvantages of pebble data
bias in selecting pebbles to measure
advantages of questionnaire
