Basic maths Flashcards
1
Q
State the strengths of using primary data
A
- Have more control over collection of data so usually more accurate
- More up-to-date data as collected directly from participants
2
Q
State the weaknesses of using primary data
A
- Time consuming and expensive
- Can be quite sensitive information so may make participants uncomfortable (ethical issue)
- May lead to research bias as the researcher is collecting it directly
3
Q
State the strengths of using secondary data
A
- Time + cost effective
- More practical: can make use of data that has already been collected
- Less personal as don’t have to ask/test participants directly
- Can often give a large sample of data
4
Q
State the weaknesses of using secondary data
A
- May be inaccurate/outated data
- May be misinterpreted
5
Q
State the strengths of quantitative data
A
- Quick and easy to analyse and make comparisons between different groups or conditions
- Allows for easy replication of measurement by others = high external reliability
6
Q
State the weaknesses of quantitative data
A
- Cannot show insight into why behaviour occurred clearly = reduced internal velidity
- From just numbers it is hard to create effective, practical applications = less useful
7
Q
State the strengths of qualitative data
A
- Can generate information about the reasons behind behaviour in detail, finding out why behaviour occurred = increased internal validity
- Not limited like numbers, people are free to contribute what they wish
8
Q
State the weaknesses of qualitative data
A
- Subjective interpretation —> different people could interperate the data differently (risk of bias) = reduced internal validity/scientific nature
- Time consuming and difficult to analyse and compare = reduced external reliability
