Structure of Studies Flashcards
How are psychological studies structured? (14 cards)
What is the aim?
What is the researcher trying to investigate/discover?
What the purpose/objective of the study is.
What is the method of the study and what does it include?
Design: Type of research (survey, observation, interview)
Participants: Where did researcher find the sample and what is the demographics? Sample size representative? Large or small?
Material: What materials are used for the research.
Procedure: The procedure/what the researcher did from start to finish?
What are the results/findings of the study?
What they found (qualitative)
+
What they found (quantitative)
What is the conclusion?
Did their results support their initial hypothesis (prediction)
What is the evaluation of the study?
Were there any ethical issues with the study?
What are some issues/limitations of the studies procedure/methodology/sample size.
If you would do the study again, what would you do differently.
What is the IV (independant variable)?
What is manipulated/changed by the researcher- what is causing the DV. (eg how much energy drinks someone has drunk)
What is the DV (dependant variable)?
Influenced by the IV, and the thing the researcher is measuring. (eg the exam results in a maths test)
What does it mean to operationalise variables?
To make your variables very specific/with precise measurments and details.
not operationalised: the group that drinks the energy drink will do worse on the exam
operationalise: after drinking 400ml of redbull, the group got below 60% on the exam.
What is a hypothesis?
A prediction of what you think will happen in the study.
A precise and testable statement about what will happen to the variables in the investigation.
(NEVER SAY ‘I’)
What is a null hypothesis?
A statement of no relationship/difference between the variables.
(eg there will be no difference in the exam scored between who drinks the energy drinks and who does not)
What is an alternative hypothesis?
A statement of the relationship/difference between variables.
(eg people who dont drink energy drinks will get a higher exam score)
What is an operationalised hypothesis?
A hypothesis in operational terms- we can measure + record.
. Variables operationilised, measured and recorded and defined as well.
What is an general (one tailed) hypothesis?
A general hypothesis, saying that something will affect something (so not null) but it will not say the direction it affects in.
What is an experimental hypothesis (two tailed)?
Basically exact same as alternate hypothesis… states the relationship between the variables and what direction it affects in (eg more or less)
