Q

Double-blind procedure

Q

Controlled experiment

A

a type of investigation in which the causal relationship between two variables is tested in a controlled environment; more specifically, the effect of the independent variable on the dependent variable while aiming to control all other variables

Q

Extraneous variables

A

variables other than the independent variable that may produce unwanted results in an experiment

24
Q

Generalisability

A

the extent to which the results of an investigation can be applied to the wider research population

25
Hypothesis
a testable prediction about the outcome of an experiment; it is written in the form of a statement and includes the variables that will be tested
26
Between subjects design
(also known as independent design) an experimental design in which participants are split into two or more groups; typically a control group and an experimental groups
27
Independent variable (IV)
the variable that the experimenter manipulates in order to observe the effect it causes on the dependent variable
28
Informed consent
ensuring participants have a thorough understanding of the procedures involved in the research they are partaking in, including potential harm or risks, and still willingly agree to participate
29
Mixed Design
an experimental design which combines elements of within-subjects and between-subjects designs
30
Non-maleficence
(also known as the no-harm principle) the principle of avoiding causing harm
31
Non-standardised testing procedures
when instructions and procedures in an experiment are not consistent for all participants, therefore affecting the results obtained
32
Objective data
data that can be observed or measured by multiple people and obtain the same results
33
Observational study
a type of study in which data is collected through careful monitoring of participants
34
Operationalisation
the process of defining variables in terms of how they will be either manipulated or measured in the experiment
35
Order effects
(also known as practice effects) a source of error in repeated-measures designs due to the order the participants participate in the experimental and control conditions
36
Participant-related variables
(also known as individual participant differences) individual participant differences that can affect the results
37
Placebo
a procedure or substance with no active treatment
38
Placebo effect
changes to an individual?s mental or physical state as a result of a false belief in the effects of a placebo substance or procedure
39
Population
(also known as research population) the group of people of interest to an experiment
40
Qualitative data
data that describes the characteristics of something; data of concepts that can be measured non-numerically
41
Quantitative data
data concerning numerical amounts; expressed numerically
42
Questionnaire
(also known as surveys) a list of questions that participants can respond to in a variety of formats
43
Random allocation
when every member of the sample has an equal chance of being assigned to each condition in an experiment
44
Random sampling
when every member of the population has an equal chance of being selected for the sample
45
Within subjects design
(also known as repeated measures design) an experimental design in which the same participants are in every condition of the experiment
46
Sample
a subset of the population, commonly referred to as the research participants
47
Sampling
the process through which the participants for a study are selected from the population of interest
48
Sampling procedures
the method of choosing an appropriate sampling procedure to reduce possible extraneous and confounding variables
49
Single-blind procedure
a procedure in which participants are unaware of which condition they have been allocated to, in order to reduce participant expectations
50
Situational variables
any environmental factor that may affect the dependent variable
51
Standardised instructions and procedures
the consistent use of instructions and procedures for all participants
52
Stratified sampling
when the population is divided into groups based upon relevant characteristics, and participants are selected from each group in proportion to how they appear in the population
53
Subjective data
data that relies on personal opinion or self-report
54
Variable
a factor or element of an experiment that may be manipulated or measured
55
Voluntary participation
the right of the participant to freely choose to willingly participate
56
Withdrawal rights
the right of the participant to leave the study at any point, without fear of consequence
