Q

what is a closed questionnaire and what can it do?

A

a questionnaire that only has one word answers like yes and no. Allows easy analysis but limits detail.

Q

what is an issue with the publication of research by the industry?

A

The questions might be phrased in a way that promotes a certain answer. Particularly by companies that are trying to assure their product is safe.

Q

what makes a laboratory experiment?

A

artificial setting, standardised procedure, high level of control over other variables and participants are aware of being in the study.

Q

what makes a natural experiment ?

A

does not directly manipulate IV, (mainly because it is unethical to do this normally), done in natural setting.

Q

what makes a quasi experiment

A

IV is naturally occurring there is already a difference in characteristics of participants, no randomised allocation of groups

21
Q

what is the repeated measures design?

A

each participant takes part in each condition which means they act as their own control

22
Q

what are the matched pairs design?

A

each participant is matched as equally as possible to another participant based on a specific criteria

23
Q

what are order effects?

A

the participants performance once they have completed the second condition may be affected because they are more practised at it

24
Q

what are participant variables?

A

each participant will vary slightly therefore there might be knock-on consequences on the results

25
Q

what is inter-rater reliability?

A

more than one observers that have the same findings

26
Q

what are the types of design of observations?

A

structured and unstructured

27
Q

what are the different techniques for observations?

A

naturalistic or controlled, overt or covert and participant or nonparticipant.

28
Q

what does overt and covert mean?

A

covert- the participants are unaware of being observed. Overt- participants know they are being observed.

29
Q

what are the types of sampling for observational studies.

A

time sampling and event sampling.

30
Q

what is the difference between time and event sampling

A

time- how much in a certain time frame. event- every time something happens

31
Q

summarize the observational study by Rosenhan(1973)

A

eight pseudo patients gained access to go to hospitals and pretend that they were mentally ill and could hear voices, once they were in they acted completely fine and observed how they and others were treated

32
Q

what is correlation?

A

refers to studies where both variables are measured instead of manipulating one and measuring the other

33
Q

what is a positive correlation?

A

the two variables increase and decrease together

34
Q

What is a negative question?

A

as one variable increases the other decreases

35
Q

What is a curvilinear correlation?

A

a correlation might begin as positive and then change and turn to negative or vice versa

36
Q

what does it mean if there is no correlation?

A

there is no clear trend in the data.

37
Q

what is a correlation coefficient?

A

the strength of a correlation is indicated by the value of r which ranges from 0-1. the direction of the correlation is indicated by by whether r is positive or negative.

38
Q

What are the strengths of a correlational method?

A

allows researcher to measure the relationship between naturally occurring variables, it can be used for stuff that would otherwise be unethical or impractical and it can indicate trends.

39
Q

what are the limitations of using correlations?

A

you cannot establish cause and effect, sometimes it may appear there is no correlation

40
Q

What is the range?

A

the difference between the highest and lowest in a set of data.

41
Q

What is the interquartile range?

A

measure the spread of scores in the middle 50% of values when they are placed in numerical order

42
Q

what is the standard deviation?

A

measures the average distance of each score away from the mean

43
Q

What is nominal data ?

A

counting data into categories, the categories are mutually exclusive

44
Q

What is ordinal data?

A

rating on a scale or ranking in order, the data can be placed in a logical order

45
Q

What is interval and ratio data?

A

there is a precise measurement, there are fixed intervals

46
Q

What is continuous data?

A

not restricted to certain values

47
Q

What is discrete data?

A

restricted to certain values, ordinal and nominal

48
Q

What are descriptive statistics?

A

summarizing sets of quantitative data, these are data tables, measures of central tendency, measures of dispersion

49
Q

what is the level of sophistication of data?

A

NOIR- nominal, ordinal, interval, ratio. from least to most

50
Q

What is the difference between interval and ratio.

A

Interval scales hold no true zero and can represent values below zero, whereas ratio has a true zero value and no negative values

51
Q

What is an operationalised variable?

A

You clearly define what you take as a measurement of the conceptual variable

52
Q

What is a conceptual variable?

A

A concept or construct
