D Mock - Research Methods Flashcards
Define the term ‘ethics’
The term ‘ethics’ refers to the moral principles that govern a person’s behaviour or how they conduct an activity.
When do ethical issues arise?
Ethical issues arise when there is a conflict between the rights and dignity of participants and the goals and outcomes of research.
What is the mnemonic for the 6 main ethical issues?
Can Do Can’t Do With Participants
What are the 6 main ethical issues?
Can - Confidentiality
Do - Deception
Can’t- Consent
Do - Debrief
With - Withdrawal (right to withdraw)
Participants- Protection from Harm
What were the ethical issues raised in Asch’s study? Give the three. Brainstorm
Deception - confederates deliberately misleading one participant.
Consent - Didn’t have the full information.
Confidentiality - Filmed study, shared online.
How can you deal with informed consent?
1) Get consent
2) Presumptive consent
3) Prior General consent
How do you deal with deception?
1) The need for deception should be approved by an ethics committee, weighing up the benefits of the study against the costs to participants.
2) Participants should be fully debriefed after the study and offered the opportunity to withhold their data.
How do you deal with the right to withdraw?
Participants should be informed at the start of the study that they can withdraw, and after the investigation they should be to,d that they can withdraw their data.
How do you deal with protection from harm?
- Avoid any risks greater than everyday life.
- Stop the study.
How do you deal with confidentiality?
Give fake names/ numbers/ initials -> non-identifiable
Before a researcher does a study, they have to identify their ______ __________ (who they want to study).
However, it can be hard to study everyone in the target population, so they may select a ______ (a smaller number of participants from the target population).
target population
sample
What does a sampling technique do?
It’s a method that aims to produce a representative sample.
What are the 5 sampling techniques?
Random
Systematic
Stratified
Opportunity
Volunteer
What is the random sampling technique?
All members have an equal chance of selection.
What is the systematic sampling technique?
When every nth member of the target population is selected.
What is the stratified sampling technique?
The composition of the sample reflects the proportions of people in certain subgroups (strata) within the target population.
What is the opportunity sampling technique?
Where participants who are most convenient or available are recruited for the study.
What is the volunteer sampling technique?
This involves participants selecting themselves to be part of the sample.
What is a STRENGTH and WEAKNESS of random sampling?
STRENGTH) No bias -> equal chance
WEAKNESS ) Sample may not be varied by coincidence
What is a STRENGTH and WEAKNESS of systematic sampling?
STRENGTH) Avoids researcher bias, usually fairly representative.
WEAKNESS) Less effective than random, as it can’t be claimed that every population member has an equal chance.
What is a STRENGTH and WEAKNESS of stratified sampling?
STRENGTH) Representative of population
WEAKNESS) Time- consuming to identify subgroups, then randomly select participants, and contact them.
What is a STRENGTH and WEAKNESS of opportunity sampling?
STRENGTH) Quick, convenient, cheaper
WEAKNESS) Difficult to generalise beyond the sample, open to researcher bias
What is a STRENGTH and WEAKNESS of volunteer sampling?
STRENGTH) Less time-consuming, requiring minimal input from the researcher.
WEAKNESS) The reward/ type of advertisement may affect variety.
What are demand characteristics?
Clues/ cues that may help participants to question the aims of the study or the experimenter’s intentions.
What might demand characteristics mean?
The participants may try to please the experimenter (the ‘please-U’ effect)
The participants may deliberately under-perform to sabotage the results of the study (the ‘screw-U effect’)
What is the IV?
Independent variable - what we change or control in an experiment
What is the DV?
Dependent variable - The result/ outcome of the study. What we measure.
What is the EV? Give an example.
Extraneous variables - anything other than the IV that will influence our results (the DV).
For example, demand characteristics.
What is naturalistic observation?
A research method in which the researcher studies behaviour in its natural setting without intervention or manipulation.
What is controlled observation?
Watching or recording behaviour in a controlled, structured environment, where some variables are managed,
Zimbardo’s experiment is an example of what type of observation?
Controlled observation
What is event sampling?
Involves the observer counting the number of times a particular behaviour occurs.
What is time sampling?
Involves the observer recording established behavioural categories in a pre-established time frame.
What is overt observation?
The participant knows they are being observed.
What is a PRO and a CON of overt observation?
PRO) No ethical issues
CON) Behaviour may not be natural/ normal
What is covert observation?
The participants are unaware they are being observed.
What is a PRO and a CON of covert observation?
PRO) High ecological validity
CON) Ethical issues
What is participant observation?
The observer becomes actively involved in the activities of the people being studied.
What is a PRO and a CON of participant observation?
PRO) Easier to understand the observer’s behaviour. High ecological validity.
CON) Difficult to record observations (reliability issues). Observer can become involved, do data may be subjective.
What is non-participant observation
Researcher observing from a distance.
Give a PRO and a CON of non-participant observation.
PRO) Observations are made as they happen, so more reliable. Lack of contact, so observer maintains objectivity,
CON) Behaviour may be recorded but the meaning behind it is unknown.
Why might it be useful to have several observers?
Strengthens results in validity (accuracy) and reliability (consistency)
What is a questionnaire?
A type of self-report method, in which people are surveyed about a topic to find out more.
What are questionnaires made up of?
Open and closed questions.
What is an open question?
Allows the respondent to say as much as they like.
They aren’t restricted in the answers they give.
What is a closed question?
A fixed choice of responses determined by the researcher.
Participants are restricted in the answers they give.
