P2 Section C (Research Methods) Flashcards
What is the abstract of a report
The abstract of a report is the first section of a psychological report consisting of a 150 word summary of the report.
What is included in the abstract of a report
Included in the abstract of a report is the aim, hypotheses, method, results, and conclusions of the report
What does the abstract of a report save researchers from doing
The abstract of a report saves researchers from reading hundreds of reports to find relevant research, instead they only need to read the abstract.
What is the introduction of a report
The introduction of a report is an overview of the research field (such as aggression) and then narrowed down to the personal piece of research being done.
Why is the funnel technique used in the introduction of a report
The funnel technique is used in the introduction of a report so broad themes and can be addressed first and then the more in-depth part of your study is explained.
What is the aims in a report
The aims in a report is the general targets of the study
What is the hypothesis in a report
The hypothesis in a report is a section stating what is going to be tested and what the expected outcome of the tests are
How is the hypothesis disclosed in a report
The hypothesis is disclosed in a report by saying the alternative and null hypothesis unambiguously and then justifying the direction of the hypothesis (either one-tailed or two-tailed)
What is the method of a report
The method of a report is a detailed section outlining how the experiment is conducted so anyone can replicate it
What is included in the method of a report
Included in the method of a report is the design, method, sample, participant, apparatus, procedure and ethics
What is the experimental design
The experimental design is the how participants are allocated to different conditions - independent groups, repeated measures or matched pairs
What is the experimental method
The experimental method is the type of experiment used to manipulate the variables to establish cause and effect such as lab experiment or field experiment
What is the sample
The sample is the way participants have been recruited for example volunteer sampling
What is the experimental procedure
Experimental procedure is a set of standardised instructions to follow in the study.
What is the results of a report
The results of a report is the section where the key findings are displayed in relation to the hypothesis
What is included in the quantitative results of a report
Included in the quantitative results of a report are the descriptive statistics (like charts), the measure of central tendency, the measure of dispersion (like standard deviation), reasoning behind choice of statistical test (like sign test)
What is included in the qualitative results of a report
included in the qualitative results of a report is thematic analysis of theme and categories in the language
What is discussion in a report
Discussion in a report is a summary of results in relation to the hypothesis and aims
What is included in the discussion of a report
Included in the discussion of a report is the comparison of own results to previous research, limitations of the research and how to improve for the future and also real-life applications of the research
What is referencing in a report
Referencing in a report is where all the sources the researcher has used to gather initial information and apparatus are credited to the founder
What is the appendices in a report
The appendices in a report is where any materials that’ve been used in the study are placed such as charts, questionnaires, consent forms, raw data and statistical calculations
What does the hypothesis predict
The hypothesis predicts the relationship between the dependent and independent variables
What must the hypothesis must be
The hypothesis must be operationalised which defines what each variable looks like
What is an example of an operationalised hypothesis
An example of an operationalised hypothesis is “aggressiveness will increase as time goes on and will be shown by more swearing”
What is the independent variable
The independent variable is the thing changed by the researcher (often the cause)
What is the dependent variable
The dependent variable is the measured result of the change
What is an alternative hypothesis
An alternative hypothesis is a testable statement of what the experimenter thinks will happen
What is a null hypothesis
A null hypothesis is a testable statement of what the experimenter predicts could happen by chance alone - opposite of alternative
What is a directional one tailed hypothesis
A directional one tailed hypothesis is a prediction of how the independent variable will effect the dependent variable, with a specified change
What is a non-directional two tailed hypothesis
A non-directional two tailed hypothesis is where direction is not stated but simply says that one factor affects another, or that there is an association or correlation between two variables
What is an extraneous variable
An extraneous variable is any variable other than the independent variable which may effect the dependent variable
What are the 3 types of extraneous variable
The 3 types of extraneous variable are participant variable, situational variable and experimenter variable
What is participant extraneous variable
Participant extraneous variable is factors like participants age and IQ which may affect results
What is situational extraneous variable
Situational extraneous variable is factors of the experimental setting and surrounding environment which may affect results like temperature or noise levels
What is experimenter extraneous variable
experimenter extraneous variable is factors of the experimenter such as their personality, appearance or their method of conducting which may affect results
What is an example of an experimenter extraneous variable
An example of an experiment extraneous variable is the gender of the researcher, as a female researcher may receive different answers than a male researcher
What is a confounding variable
A confounding variable is any uncontrolled extraneous variable which negatively affects results
What are demand characteristics
Demand characteristics are features of a piece of research which allow the participant to work out the aims or hypotheses of a study which may make participant change their behaviour
What are investigator effects
Investigator effects are ways in which researchers can unconsciously influence the participants response in a study
What is an example of investigator effects
an example of investigator effects is the researcher being biased in their interpretation of their data and so finding what they expect to find, also investigator’s accent or tone may effect participants as they may respond differently to a stern voice
How can researcher avoid investigator effects
researcher can avoid investigator effects by doing a double-blind study where the researcher and participant both don’t know what condition they’re in (e.g. don’t know whether medicine is given or a placebo)
What is independent groups design
independent groups design is where participants are allocated into separate groups for each condition
What is repeated measures design
repeated measures design is where participants are allocated into the same group for every condition
What is matched pairs design
Matched pairs design is where participants are allocated into two separate groups matched in pairs for qualities like IQ or age and one person from each pair takes part in a separate condition
Strengths of independent groups
Strengths of independent groups are less prone to demand characteristics since participants do one condition and so are less likely to guess aim of study
Weakness of independent groups
Weakness of independent groups is prone participant extraneous variables since participants in one condition may be more intelligent than those in another, causing different results
Strengths of repeated measures
Strengths of repeated measures are less prone to participant extraneous variables since the same people are in both conditions and less participants needed as they provide both sets of data
Weakness of repeated measures
Weakness of repeated measures are order effects since participant may be fatigued or bored which affects the results of second condition or participants may perform better in the second condition as they have had practise from the first and also prone to demand characteristics since they take part in all conditions so have an idea of what is being measured
How can you reduce order effects
Order effects can be reduced by counterbalancing, whereby half participants do condition A first followed by condition B, then the other half do condition B first then condition A
Strengths of matched pairs
Strengths of matched pairs are there are no order effects since different participants do each condition and also participants are matched so less prone to participant variables as there isn’t individual differences affecting the results
Weakness of matched pairs
Weakness of matched pairs are it is time-consuming to match participants and also matching is difficult since all participants will have different variables effecting their performance
