Sampling Strengths & Weaknesses Flashcards
Longitudinal study definition
Gathers data from a single group over a long period of time
Longitudinal study strengths
- Produce qualitative and valid data focused on people’s interpretation of reality (verstehen)
- Allows sociologists to document how the influence of social factors influence people
- Allow hypotheses to be modified
Longitudinal study weaknesses
- Original sample may become too research friendly and end up working out what the researcher wants and giving it to them, creating bias
- The original sample may drop out, move away or die and the remaining members may not be representative of the group originally studied
- The original research team may lose sight of the original goals
- Such research is expensive
Ethnography study definition
The study of people in their own environment through the use of methods such as participant observation and face-to-face interviewing
Ethnography study strengths
- More realistic picture
* Uncovers extremely valuable insight
Ethnography study weaknesses
- Requires time.
- Creating a normal environment is not always easy.
- It’s more difficult to recruit
Quantitative data definition
Statistical or numerical data that can be presented in graphs, tale, percentages etc
Quantitative data strengths
- Has comparative value
- Can be observed for patterns, trends, correlations and so on
- Used to establish cause and effect relationships in order to deduce ‘facts’ about human behaviour
Quantitative data weaknesses
- Not much detail provided in the studies
- Using secondary data is often not accurate
- E.g., official statistics are often unaware of the crime rate amongst middle class (white-collar crime)
Qualitative data definition
Information that is usually expressed in the words of the research subjects. Focused on insight into people’s feelings and attitudes.
Qualitative data strengths
- Richer in detail and validity
- Lets research subjects speak for themselves
- Gives insight to people’s behaviour
- Sometimes people conduct social experiments themselves
- Secondary sources are also used
- This is good, as there is a variety of ways to obtain data, resulting in a more valid outcome
Qualitative data weaknesses
- Difficult to sort through the data and pick out the important parts
- Time consuming, particularly in instances such as unstructured interviews
- The participant may ramble on and not provide much useful information
- Research subjects could lie about some things
- Secondary sources are not always reliable
