6
Q

Give 4 strengths of cross-sectional studies.

A

1) High validity due to data being gathered quickly and so findings will be reported at the time making research more relevant
2) Higher ethics due to being less intrusive on the participants’ lives and so their privacy is not compromised
3) Easier to find and withhold participants due to the research being done at the time, compared to longitudinal studies with high drop out rates
4) High generalisability due to large sample gathered

7
Q

Give 3 weaknesses of cross-sectional studies.

A

1) Low validity due to different people being used and so participant variables will affect overall results
2) Low validity due to the cohort effect as research could be affected by the particular time or place due to being unique situations
3) Low generalisability due to being carried out in a particular time or place and so causing sample to consist of particular type of people, decreasing representativeness
