Research Methods Flashcards
What is an aim?
The intent of a study
What is a hypothesis?
What you think you are likely to find out
What does operationalising a variable mean?
Defining a variable so that it is easy to understand and easily measured
What is a Pilot Study?
A small scale study conducted before the actual study to find issues that need to be changed
What is a random sample ?
A sample where every member has the same chance of being selected
What are some evaluation points for using a random sample?
Positive-no bias, not time-consuming
Negative-not likely to be representative
What is a systematic / quasi-random sampling method ?
Participants names are out into a list and every nth person is selected
What are some evaluation points of using systematic/quasi-random sampling ?
Positive-efficient and free from bias
Negative-not likely to be representative
What is a stratified sample ?
Breaking the population into groups and take a proportional sample reflecting the population
What are some evaluation points of using stratified sampling ?
Positive-representative
Negative-more time consuming than other sampling methods
What is quota sampling ?
Using a stratified method but select the individual participants using an opportunity sample rather than a random sample
What are some evaluation points of using a quota sampling method ?
Positive-representative
Negative-biased and time consuming
What is cluster sampling ?
Selecting a geographical area and take a random or stratified sample from people in that area
What are some evaluation points of using a cluster sampling method ?
Positive-representative of the area
Negative-may not be representative of larger areas
What is snowball sampling ?
Building a rapport with one participant and asking them to get more people to participate
What are some evaluation points of using snowball sampling ?
Positive-can get access to difficult groups such as criminals
Negative-not representative,small sample sizes
What is an opportunity sampling method ?
Asking people who are available at the time of the study to participate in the study
What are some evaluation points of using opportunity sampling ?
Positive-easy and not time-consuming
Negative-not representative, biased
What is volunteer sampling ?
Posting an advert and those who respond are participants in the study
What are some evaluation points of using volunteer sampling ?
Positive-convenient
Negative-not representative
What is primary data ?
Data collected by the researcher themselves for the purpose of their study
What are some advantages of using primary data ?
-specific to the study
-can use the format that is right for the overall study eg quantitative or qualitative
-higher validity
What are some disadvantages of using primary data ?
-could include bias
-time consuming
What is secondary data ?
Data that has been previously collected by another researcher for the purpose of a previous study
What are some advantages of using secondary data ?
-Quick and easy to access
-Less likely to be bias
-Allows for comparisons to be made from different pieces of research
What are some disadvantages of using secondary data ?
-It is not specific to the study that you are conducting
-It may not be valid
What is quantitative data ?
Data that is numerical e.g. percentages
What are some advantages of using quantitative data?
-It is objective
-It is easy to compare to other data to find patterns and trends
What are some disadvantages of using quantitative data?
-It is not in depth
-It does not provide causation to the trends identified
What is qualitative data ?
Data that is not in the form of numbers
e.g. Newspaper articles
What are some advantages of using qualitative data ?
-It is in depth
-It has more details about the information gathered
What are some disadvantages of using qualitative data ?
-It is subjective
-It is not as easy to compare to previous or future studies
What is meant by a practical consideration ?
Considerations that need to be made involving how the research is going to take place and whether it will be possible to conduct
What is meant by an ethical consideration ?
Considerations that have to be made about the morality of the research and whether it should or shouldn’t be done
What is meant by a theoretical consideration ?
Choosing the right method to gather data that correlates with whether the researcher is a positivist or an interpretivist
What are some examples of practical issues ?
Time, Cost, Funding, Personal skills and characteristics, Subject matter and Research opportunity
Why is time seen as a practical issue ?
Different methods might take more time to complete than the researcher has this is often found in methods such as interviews and longitudinal studies
Why is cost seen as a practical issue ?
The longer a method takes the more it costs this is due to factors such as having to pay for staff and resources, staff training for methods such as interviews also have a high cost
Why is funding seen as a practical issue ?
If the research is being funded it may limit the flexibility of the research or the methods that could be used, funding could also be cut or may force the research in a specific direction
Why are personal skills and characteristics seen as a practical issue ?
It may be more difficult to build a rapport with certain groups based on your age, gender and ethnicity
Why is subject matter seen as a practical issue ?
The method chosen has to revolve around the subject matter for example an observation could not be used to study domestic violence, unstructured interviews would be a better method however it may not suit the researcher
Why is research opportunity seen as a practical issue ?
Some groups may be more difficult to access due to a gatekeeper such as studying education within primary schools
What is meant by consent ?
Making sure that participants give permission to be part of the study
What is meant by confidentiality ?
Making sure that the participants’ information is kept secure and not shared without consent
What is meant by deception ?
When a participant is not told the true aim of the study, or they are being mislead
What is meant by protection from harm ?
Making sure that participants don’t experience physical or psychological harm due to the study
What is meant by illegality ?
When the law is broken during the study
What studies can be used as examples of studies with ethical issues ?
Milgram - shock experiment
Bandura - the bobo doll
Rosenthall and Jacobson - Self fulfilling prophecy
Humphreys - Tea room trade
Outline the procedure of Milgrams shock experiment
The participants were told to act as teachers and shock the learners ( a confederate/actor ) every time they got a question wrong
Outline the ethical issues with Milgram’s shock experiment
Deception-participants were not told that the learners were confederates and they were not told that the electric shocks were fake
Protection from harm-the participants experienced psychological harm during the study they showed signs of distress in extereme cases participants experienced seizures
Outline the procedure of Bandura’s bobo doll study
Half of the children watched an adult playing with the bobo doll violently and the other half watched “normal” behaviour towards the bobo doll, the children were then put into a room full of toys and told to play, the group who were shown the violent behaviour copied the adult
Outline the ethical issues with Bandura’s bobo doll study
deception-the children were unaware that they were taking part in a study
consent-the children were unable to give informed consent due to their age
