Sampling

Question 1

Pros + cons of random sample

Answer 1

+ limited researcher bias - so will be representative + generalised to TP
- unrepresentative sample - lacks population validity
- time consuming - not representative to TP so cannot generalised findings

Question 2

P + C of opportunity sample

Answer 2

+ quick and easy method = practical method to use COMPARE to stratified sample
+ ethical = p.pants are considered and research is not being forced upon them
- biased sample = unrepresentative + not generalisable to TP

Question 3

P + C of volunteer sample

Answer 3

+ practical
+ ethical = consents are received to take part in the research
- bias sample = can be bias and unrepresentative + not generalised to TP

Question 4

P + C of systemic sample

Answer 4

+ limited searcher bias = spread evenly across TP = representative + generalised
- unrepresentative sample = cannot generalised
- time consuming = not practical as may not be relevant anymore once ample has been gathered = can’t generalise findings

Question 5

P + C of stratified sample

Answer 5

+ representative sample = divided into groups = representative + generalised
- time consuming = will take long time + not practical
