25
Convenience sampling
a sampling technique that involves selecting readily available members of the population
26
Random sampling
A sampling technique that uses a procedure to ensure every member of the population has the same chance of being selected
27
Stratified sampling
A sampling technique that involves selecting people from the population in a way that ensures that its strata are proportionally represented in the sample
28
Allocation
is the process of assigning participants to experimental conditions or groups
29
Extraneous variable
any variable that is not the IV but may cause an unwanted effect on the DV
30
Confounding variable
a variable that has directly and systematically affected the DV, apart from the IV
31
Situational variables
any environmental factor that may affect the dependent variable
32
Participant-related variables
characteristics of a study’s participants that may affect the results
33
Order effects
the tendency for the order in which participants complete experimental conditions to have an effect on their behaviour
34
Placebo and Placebo effect
Placebo an inactive substance or treatment Placebo effect is when participants respond to an inactive substance or treatment as a result of their expectations or beliefs
35
Experimenter effect
When the expectations of the researcher affect the results of an experiment
36
Non-standardised instructions and procedures
when directions and procedures differ across participants or experimental conditions
37
Demand characteristics
things in an experiment that may signal to a participant the intention of the study + influence their behaviour
38
Counterbalancing
a method to reduce order effects that involves ordering experimental conditions in a certain way
39
Single-blind procedure
a procedure in which participants are unaware of the experimental group or condition they have been allocated to
40
Double-blind procedure
a procedure in which both participants and the experimenter do not know which conditions or groups participants are allocated to
41
Primary and secondary data
Primary data is collected first-hand by a researcher Secondary data is sourced from others’ prior research
42
Quantitative and qualitative data
Quantitative data is expressed numerically Qualitative data is expressed non-numerically
43
Objective and subjective data
Objective data is factual data that is observed and measured independently of personal opinion Subjective data is data that is informed by personal opinion, perception, or interpretation
44
Systematic errors
Errors in data that differ from the true value by a consistent amount
45
Random errors
Errors in data that are unsystematic and occur due to chance
46
Repeatability
The extent to which successive measurements or studies produce the same results when carried out under identical conditions within a short period of time
47
Reproducibility
The extent to which successive measurements or studies produce the same results when repeated under different conditions
48
Validity
The extent to which psychological tools and investigations truly support their findings or conclusions
49
Internal validity
The extent to which an investigation truly measures or investigates what it claims to
50
External validity
The extent to which the results of an investigation can be applied to similar individuals in different settings
51
Conclusion
A statement that summarises the findings of a study, including whether the hypothesis was supported or rejected
52
Beneficence
When research is considered through the scope of maximising the benefits to society while minimising harm to others. Research must be weighed against the potential risks or discomfort to participants.
53
Integrity
Involves the researcher’s commitment to the honest conducting and reporting of research. Also relies upon scrutiny of the research & its procedure so that the knowledge & understanding gained through research can be trusted in its broader application
54
Justice
Ensures fair treatment for all, from selection through to result collection
55
Non-maleficence
Also known as the ‘no harm principle’. If potential harm/discomfort is involved in research, the harm/discomfort does not outweigh the potential benefit(s) that could eventuate
56
Respect
Shown through the consideration of an individual’s welfare, but also through the appreciation of participant’s uniqueness, autonomy and freedom of expression.
57
Confidentiality
A participants right to privacy with regard to access, storage and disposal of information collected about them related to the study. No disclosure of information unless written consent is obtained by the participant
58
Informed consent
The researcher must obtain written permission before an experiment commences. The consent form must inform the participants about their rights, any possible psychological or physical harm they may encounter and research procedures present in the study
59
Deception
Should only occur if necessary. As giving participants information before a study may influence their behaviour & hence affect results, deception can be used in such cases. If this does occur, researchers must ensure all participants are thoroughly debriefed
60
Debriefing
Participants are informed of the study’s true purpose once the experiment has ended. All mistaken attitudes or beliefs are corrected and all deception explained. An opportunity giving any information regarding the study must be provided, including additional support & counselling
61
Voluntary participation
A participant willingly decides to take part in an experiment without experiencing any pressure or coercion. There are also no negative consequences if they decide not to participate
62
Withdrawal rights
A participants right to leave a study at any time without negative consequences or pressure to continue. Must be adhered to during and after the experiment. If a person feels uncomfortable during any activity, even a follow-up, or wish to remove their results, they can do so without consequence.
