Q

What is a control group?

A

The control group is the group in research which is not presented with the independent variable. The control group is used as a basis for comparison with the experimental group.

A

Counterbalancing process in a repeated measures design designed to eliminate order-effects. Conditions A, B and C would be presented in a different sequence to different groups of participants.

Q

What is a double-blind procedure?

A

A double-blind procedure is an experimental design that ensures that neither researcher nor participants are aware of which participants are in the control group and which are in the experimental group. This eliminates both experimenter and participant expectations as possible confounding variables.

Q

What are ethical principles?

A

Ethical principles are the code of ethics designed to protect participants from psychological and physiological harm. These include: confidentiality; debriefing; deception in research; informed consent; voluntary participation; withdrawal rights.

Q

What is debriefing?

A

Debriefing occurs after the experiment where researchers inform participants of their findings and clear up any misunderstandings or questions and experimenters tell participants the true nature of the research

Q

What is deception in research?

A

Deception is failing to give participants all the information. Deception should only be used if disclosure of the nature of the study will jeopardise the study and findings and if used, there must be adequate debriefing

Q

What is informed consent?

A

Informed consent is the ethical basis for psychological treatment or experimentation, require that the subject (or client) is fully aware of all procedures and their likely and possible effects, and participates on a voluntary basis.

Q

What is matched participants?

A

Matched participants involves a subject selection procedure which attempts to eliminate confounding variables by ‘matching’, on key characteristics, each individual in the experimental group with an individual in the control group

Q

What is an experimental group?

A

An experimental group is the group of research participants which is exposed to the independent variable. The results are compared with the control group so that the effects of the independent variable can be determined

22
Q

What is an independent variable?

A

The independent variable is the variable that is manipulated by the experimenter who then measures resulting changes in the dependent variable

23
Q

What are measures of central tendency?

A

Measures (mean, median and mode) that tell us how the data are clustered near the central point of the dataset.

24
Q

What is a mean?

A

The mean is the average of all the scores, calculated by adding up all the scores and dividing that total by the number of scores

25
Q

What is a median?

A

The median is the score that occurs exactly halfway between the lowest and the highest score

26
Q

What is a mode?

A

The mode is the most commonly occurring score in the dataset

27
Q

What are observational studies?

A

Observational studies are research in which there is no manipulation of the independent variable by the researcher

28
Q

What is operationalisation of variables?

A

Operationalisation is the quantification of a variable

29
Q

What is order effect?

A

Order effects are changes in results caused by the sequence of performing tasks in a test; often ascribed to practice- or boredom-effects

30
Q

What is participant effect?

A

A participant effect is characteristics of the participants becoming a confounding variable and influencing the value of the dependent variable

31
Q

What are participants’ rights?

A

Participants’ rights are ethical considerations including the right to informed consent, debriefing and withdrawal rights

32
Q

What is a placebo?

A

A placebo is a variable other than the independent variable that causes a change in the value of the dependent variable due to he participant’s belief that it will have an effect

33
Q

What is the placebo effect?

A

The placebo effect refers to the participants’ behaviour being influenced by their expectations of how they should behave, caused by the belief that they have received some treatment.

34
Q

What is a population?

A

A population is the group of people about whom we wish to draw conclusions

35
Q

What is a p-value?

A

The p-value is the likelihood that a result would be achieved by chance alone

36
Q

What is qualitative data?

A

Qualitative data is descriptions of the characteristics of what is being studied

37
Q

What is quantitative data?

A

Quantitative data is measurements (numerical information) about the variables being studied

38
Q

What is a questionnaire?

A

A questionnaire is a form of self-report survey

39
Q

What is random allocation?

A

Random allocation is a subject selection procedure where all participants who have been selected for an experiment have an equal chance of being in the E-group or C-group

40
Q

What is a sample?

A

A sample is the members of the population that have been chosen to take part in the research in order to represent the population

41
Q

What is a convenience sample?

A

Convenience sampling is the process of selecting participants who are easily obtainable

42
Q

What is a random sample?

A

Random sampling is a sampling procedure in which every member of the population has an equal chance of being selected

43
Q

What is a stratified random sample?

A

Stratified random sampling is a method of sampling that involves the division of a population into smaller groups known as strata, which are based in members’ shared attributes or characteristics

44
Q

What is a stratified sample?

A

Stratified sampling is a sampling process by which the effects of a certain variable can be eliminated as a possible confound in an experiment

45
Q

What is the scientific method?

A

The scientific method is the structured process that is used in all psychological research

46
Q

What are self-reports?

A

S

47
Q

What is a single-blind procedure?

A

A single-blind procedure is an experimental design in which either the participants or the researcher does not know which participants a in the experimental group

48
Q

What are standardised instructions and procedures?

A

Standardised instructions and procedures are the system of using the same words, actions and materials despite being administered by different researchers. A process of eliminating possible confounds.

49
Q

What is statistical significance?

A

A result is called statistical significant when the likelihood of a finding occurring by chance is less than 5 in 100

50
Q

What are variables?

A

Variables are describable or quantifiable properties measured in research, they may be independent; dependent; confounding; controlled and extraneous

51
Q

What is a confounding variable?

A

A confounding variable is a variable other than the independent that has a systematic effect on the value of the dependent variable (it acts like a second, unwanted, independent variable).

52
Q

What is a controlled variable?

A

C

53
Q

What is an extraneous variable?

A

An extraneous variable is any variable other than the IV or DV - these may be confounding, controlled or neutral variables.
