Laboratory Experiment
Research is carried out in a highly controlled enviroment, often contrived. Casual conclusions can be drawn.
1 of 31
Field Experiment
Research is carried out in a natural enviroment but still has a high degree of control. Many more Ev's which can be difficult to control.
2 of 31
Quasi (Natural) Experiement
Researcher has no control over the IV however they will still measure the DV, Therefore the IV occured naturally.
3 of 31
Non-participant Observation
Researcher observes behaviour but does not get involved in the activity.
4 of 31
Content Analysis
Qualitative materials are analysed for themes and categories, can then be turned into quantitative data.
5 of 31
Structured Interviews
Interviews that follow a set format so additional questions can't be asked.
6 of 31
Open Questionnaire
Can contain both qualitatve and quantitative questions, open-ended questions require more thought and more than a simple one-word answer.
7 of 31
Closed Questionnaire
Can contain both qualitatve and quantitative questions, Closed-ended questions can be answered by a simple yes or no.
8 of 31
Semi-structured Interviews
Researcher asks a number of set questions but is able to take the interview in a different direction if needed.

Correlational Analysis
Technique for looking at the strength of a relationship between two co-variables, meaning two variables that vary together.
10 of 31
Case Study
Normally a longitudinal study where a person or group of people are studied in depth.
11 of 31
Self-reports
When people provide information about themselves.
12 of 31
Longitudinal research
Research that is carried out over a period of time.
13 of 31
Correlation
Determining the extent of an association between two variables
14 of 31
Correlation Coefficient
A number between -1 and +1 that tells us how closely to co-variables in a correlation analysis are associated.
15 of 31
Curvilinear Correlation
A non-linear relationship between co-variables.
16 of 31
Intervening variable
A variable that comes between two other variables which is used to explain the association between these two variables
17 of 31
Linear Correlation
A systematic relationship between co-variables that is defined by a straight line.
18 of 31
Scatter Diagram
A graphical representation of the association between two sets of scores.
19 of 31
Significance
A statistical term indicating that the research findings are sufficiently strong for us to accept the research hypothesis under test.
20 of 31
Cross-sectional Study
One group of participants representing one section of society are compared with participants from another group.
21 of 31
Internal Reliability
Extent to which a measure is consistent within itsself.(Repeat readings to get same results).
22 of 31
External Reliability
The extent to which a measure varies from one use to another.(Redoing the test outside the setting).
23 of 31
Inter-rater Reliability
If the measure depends upon interpretation of behaviour, we can compare the results from two or more raters.
24 of 31
Test-retest Reliability
The measure is administered to the same group of people twice.
25 of 31
Split-half Reliability
Splitting a test in two halves, and comparing the scores in both halves
26 of 31
Sampling
The selection of participants from the sampling frame with the aim of producing a representivite selection of people from that group.
27 of 31
Target Population
The group of people that the researcher is intrested in and from whom a sample is drawn. Also the group of whom generalisations can be made.
28 of 31
Sampling Frame
A list of participants from the target population from which a sample is drawn.
29 of 31
Random Sample
A sample of participants produced by using a random technique so that every member of the target population has an equal chance of being selected.
30 of 31
Opportunity Sample
A sample of participants produced by selecting people who are most easily available at the time of the study.
