Research Methods Flashcards
How many marks is question 1 worth and what do you have to do?
4 marks, summarise a table of data, graph or chart
Qualitative
Produces textual information = greater detail of data
Quantitative
Produces numerical data that can be displayed in a table or graph, reveals patterns and trends but not reasons why
Primary data
Data the sociologist collects themselves
Secondary data
Data that is already collected and available to sociologists
Validity
How true or accurate the research is
Reliability
The extent to which if we repeat the experiment, would we get the same results?
Representativeness
The extent to which the sample selected is a fair reflection of the target population
Generalisability
Ability to make claims about the wider population from the research findings
What factors might influence the topics studied by sociologists?
-interests and values of the researcher
-access to research subjects
-current debates in the academic world
Operationalise
To define something so you can accurately measure it
What key concept is operationalising essential for?
Validity
Gatekeeper
A point of contact who can put you in contact with the participants you wish to research
Strengths and weaknesses of random sampling
+reduces bias
+equal chance of being chosen
-minority groups might not be presented
-could result in similar participants being selected
Strengths and weaknesses of systematic sampling
+reduces bias
+equal chance of being chosen
-time consuming
-sampling frame wont always provide useful information
Strengths and weaknesses of stratified sampling
+can ensure each group is represented
+not biased
-time consuming
-if some groups have a larger number of people = more likely to be biased
Strengths and weakness of quota sampling
+more representative
+easy to set targets
-researcher may be biased
-numbers might not represent time frame
Strengths and weaknesses of snowball sampling
+useful when there is no sampling frame
+good for studies including range of different people
-not representative
-biased/subjective
Strengths and weaknesses of purposive / opportunity sampling
+useful when there is no sampling frame
+good when there is a specific type of person needed
-not representative
-biased/subjective
Strengths and weaknesses of volunteer sampling
+useful when there is no sampling frame
+easy : can get a large sample
-sample made up of same type of people
-biased/subjective
What is a random sample?
Every member of the target population has an equal chance of being selected for the sample
What is a stratified sample?
Every ‘nth’ member of the target population is selected for the sample
What is a systematic sample?
To obtain this sample, different subgroups in the target population are identified, then people are randomly selected from these subgroups in the proportion to their numbers in the target population
What is a quota sampling?
Researcher has a clear idea of the sample they want, they will pick participants that meet their criteria, choosing individuals or cases that fit the nature of the research
