Q

What is a condition?

A

An experiment is usually organised so there are two trials, after which the performances of the participants are compared; these are the conditions of the experiment

Q

What is an experiment?

A

A research method in which the researcher tries to control all variables other than the independant variable (IV) and dependent variable (DV); this allows the researcher to identify a cause-and-effect relationship between the IV and DV

Q

What are order effects?

A

When a participant’s performance in the second condition of an experiment is affected because they have already done the first condition. They may do better because of practise or worse because of tiredness. This may happen in a repeated measures design

Q

What are participant variables?

Q

What is counterbalancing?

A

An arrangement in which half of the participants in an experiment are given the conditions in one order (A followed by B) while the other half are given them in the opposite order

Q

What is ecological validity?

A

The results of the investigation can be said to apply to real-life behaviour; they are an accurate account of behaviour in the real world

Q

What is a sample?

A

The small group of people who represent the target population and who are studied

26
Q

What are sampling methods?

A

Strategies used by researchers to obtain people from the target population to take part in their studies

27
Q

What is a stratified sample?

A

The different subgroups in the target population are identified; then people are selected randomly from these subgroups in proportion to their numbers in the target population

28
Q

What is a systematic sample?

A

Every ‘nth’ member of the target population is selected for the sample

29
Q

What is target population?

A

The large group of people the researcher wishes to study

30
Q

What are closed questions?

A

A question where the possible responses are fixed, often as ‘yes’ or ‘no’ as the options

31
Q

What is a questionnaire?

A

A set of standard questions about a topic that is given to all the participants in the survey

32
Q

What is a survey?

A

A method used for collecting information from a large number of people by asking them questions, either by using a questionnare or in an interview

33
Q

What is an open question?

A

A question where the person answering cana give any repsonse they like

34
Q

What is an interview?

A

A method in which a researcher collects data by asking questions directly

35
Q

What is a structured interview?

A

All the questions are pre-set, given in a fixed order, and every interviewee is asked the same questions

36
Q

What is an unstructured interview?

A

Only the first questions is set and all the other questions are determined by the answers of the interviewee

37
Q

What is a case study?

A

An in-depth investigation of an individual, a small group, or an organisation

38
Q

What are categories of behaviour?

A

The seperate actions that are recorded as examples of the target behaviour

39
Q

What is an observation study?

A

A method of collecting information about behaviour by watching and recording people’s actions

40
Q

What is inter-observer reliability?

A

How closely the record sheets of two or more people match

41
Q

What is correlation?

A

A technique used by researchers to establish the strength of a relationship between two variables

42
Q

What is a positive correlation?

A

A relatioship between two variables in which, as the value of one variable increases, the value of the other variable also increases

43
Q

What is a relationship?

A

A connection or association between two or more variables

44
Q

What is a scatter diagram

A

A type of graph for representing correlations

45
Q

What is negative correlation?

A

A relationship between two variables, as the value of one variable increases, the value of the other variable decreases

46
Q

What is no correlation?

A

There is no relationship between two variables

What is the quantitative method?

A

Any method which provides numerical data

54
Q
