Topic 7 - Research Methods Flashcards
What is a Lab experiment
These are experiments that take place in controlled environments and aim to use the scientific method to test a specific hypothesis. This is then used to find a cause-and-effect relationship between two variables. (positivists)
P advantages and disadvantages of Lab Experiments
advantages
-Attractive to funding bodies due to their scientific nature.
-Researchers can easily conduct the experiment as respondents come to them, so they don’t have to travel
disadvantages
-Often small scale
-Time consuming
- cannot be used to study the past
E advanatges and disadvantages of Lab Experiments
adavtanges
-If informed consent is given, no deception is involved
disadvantges
-Many experiments often conceal the real aims of the research.
-Therefore, informed consent is not always fully given.
T advantges and disadvnatges of Lab experiments
advantages
-Highly reliable, as variables are easily controlled, produces quantitative data and is a very detached and objective method
disadvantges
-Lack validity due to ‘Hawthorne Effect’
-As they’re small scale, they’re often not representative.
Lab experiments exmaple:
Milgram - Obedience to Authority - electric shock experiment (1974)
What is a Field experiment
Researchers manipulate an independent variable and measure a dependent variable in the natural environment.
Interpretivists
P advatntages and disadtanges of feild experiements
advatnges
-Larger scale research than lab experiments
disadvatnges
-Less control over variables
-Few situations can be adapted to become field experiments
-lack of research opportunity
E advatnges and disadvantges of feild experiments
-Possibly less hierarchical than lab experiments
-Deception
-Lack of informed consent
T advatnges and disadvantes of feild experiments
-Less artificial
-Highly valid
-Lower reliability in comparison to lab experiments
Example of feild experiemnts
Rosethal and Jacobson - Pygmalion in the classroom (1968)
What are questionares
A set list of questions, asked in the same way every time. They are usually self-completion but can be done over the phone or face-to-face Usually consist of mainly closed questions which creates quantitative data. Can have open questions as well
positivists
P advantages and disadvantges of questionares
-Quick and cheap to carry out
-Can be sent to respondents in a variety of ways e.g. email, post, phone call
-Gather large quantities of data
- access to subjects is easy
-easy to quantify the results
-May have a low response rate
-People may not be honest when filling it out
-Questions are inflexible, unlike unstructured interviews
-Only ‘snapshots’ of reality in one moment in time
E advatnges and disadvantages of questionares
-Informed consent given
-Neither researcher or respondents are put at any risk
-May ask sensitive/intrusive questions
T advatnges and disadvantages of questionaress
-Highly reliable
-Highly representative as they study a large sample
-Positivists argue they are objective and scientific as the sociologist’s personal involvement is kept to a minimum.
-Not very high in validity
-Questions asked may impose the researcher’s meanings
- representativeness may be undermined by low response rates
exmaple of questionaress
2011 census
What is a structred interview
An interview that follows a list of pre-set questions Interviewees choose from a limited list of possible answers They are usually done face-to-face or over the phone.Usually consist of mainly closed-ended questions which creates quantitative data
positivists
P advantages and disadvantges of structured interview
-Relatively quick to carry out as there are fixed questions
-can cover quite large numbers of people because they are quick and fairly cheap to administer
-Results are easily quantified because they use closed-ended questions with pre-coded answers.
-Employing and training interviewers is costly
-Research subjects may not be open
-Inflexible - makes it impossible for the interviewer to pursue any interesting leads that may emerge.
E advnatges and disadvantges of structured interviews
-Informed consent given
-Neither researcher or respondents are put at any risk
-Sensitive questions may be asked which can cause ‘psychological harm’.
T advnatges and disadvantes of structured intervioews
-Highly reliable due to fixed questions
-Larger scale than unstructured interviews, making it more representative
-Lacking validity due to fixed questions
exmaple of structured interview
Young and Wilmott - Family and Kinship in East London (1962)
What are unstructured interviews
An interview that asks mainly open-ended questions. There are no fixed set to ask every person. They produce qualitative meaningful data Guided by the interviewee as well as the interviewer Free-flowing, so similar to a natural conversation A strong relationship is built between the interviewer and interviewee
interpretivists
P advatnges and disadvantges of unstructured interview
-Easy to carry out, as it just like a conversation
-Cheap to carry out
-Time consuming compared to qualitative methods
-Requires good interpersonal skills
E advatages and disadvantges of unstructured interviews
-Good for sensitive topics
-Less hierarchical than structured interviews
-In depth answers makes there more potential to harm respondent if confidentiality is harmed.
T advantges and disadvantes of unstaructured interviews
-Highly valid as interviewer builds a rapport with interviewee
-Researcher can adapt questions based on the responses they’re getting
-Typically, lowly reliable
-Not very representative
Example of unstructured interviews
Dobash and Dobash - Violence Against Wives (1980)
What are group interviews
the researcher talks to a group of people at the same time, rather than discussing with individuals.
interpretivists
P advantges and disaadvnatges of group interviews
Saves time talking to a large group of people at the same time.
Researcher will have to be trained to know how to work with a group.
Ethical advnatges and disadvbatges of group interviews
People may be more open to share with others who feel similarly about a certain topic
Deception may have to be involved
T advantages and disadvnatges of group interviews
reliable as can be repeated with same people
Lack of validity due to social desirability
Example of group interviews
Willis - Learning to Labour (1977)
