Alternate hypothesis
A testable statement about the relationship (difference, association etc.) between two or more variables.
1 of 31
Calculated value
The value of a test statistic calculated for a particular data set.
2 of 31
Case study
A research method that involves a detailed study of a single individual, institution or event. Case studies provide a rich record of human experience but are hard to generalise from.
3 of 31
The process of placing quantitative or qualitative data in categories.
4 of 31
Concurrent validity
A means of establishing validity by comparing an existing test or questionnaire with the one you are interested in.
5 of 31
Content analysis
A kind of observational study in which behaviour is usually observed indirectly in visual, written or verbal material. May involve either qualitative or quantitative analysis, or both.
6 of 31
Correlation coefficient
A number between -1 and +1 that tells us how closely the co-variables in a correlational analysis are related.
7 of 31
Critical value
In a statistical test the value of the test statistic that must be reached to show significance.
8 of 31
Degrees of freedom
The number of values that are free to vary given that the overall total values are known.
9 of 31
Ecological validity
The ability to generalise a research effect beyond the particular setting in which it is demonstrated to other settings.
10 of 31
A method of gaining knowledge which relies on direct observation or testing, not hearsay or rational argument.
11 of 31
Face validity
The extent to which test items look like what the test claims to measure.
12 of 31
The possibility that a statement or hypothesis can be proved wrong.
13 of 31
Inter-observer reliability (inter-rater reliability)
The extent to which there is agreement between two or more observers involved in observations of a behaviour.
14 of 31
Levels of measurement
Refers to the different ways of measuring items or psychological variables; the lower levels are less precise.
15 of 31
Mundane realism
Refers to how a study mirrors the real world. The research environment is realistic to the degree to which experiences encountered in the research environment will occur in the real world.
16 of 31
Null hypothesis
An assumption that there is no relationship/ no cause and effect
17 of 31
One-tailed test
Form of test used with a directional hypothesis.
18 of 31
‘A shared set of assumptions about the subject matter of a discipline and the methods appropriate to its study’ (Kuhn, 1962).
19 of 31
Probability (p)
A numerical measure of the likelihood or chance that certain events will occur. A statistical test gives the probability that a particular sample did not occur if the null hypothesis for the population was true, i.e. there was no real effect.
20 of 31
Is consistency- the consistency of measurements. We would expect any measurement to produce the same data if taken on successive occasions.
21 of 31
A statistical term indicating that the research findings are sufficiently strong to enable a researcher to reject the null hypothesis under test and accept the research hypothesis.
22 of 31
Statistical test
Procedures for drawing logical conclusions (inferences) about the population from which samples are drawn.
23 of 31
Temporal (historical) validity
Concerning the ability to generalise a research effect beyond the particular time period of the study.
24 of 31
Test statistic
The name given to the value calculated using a statistical test. For each test this value has a specific name such as S for the sign test.
25 of 31
Test-retest reliability
The same test or interview is given to the same participants on two occasions to see if the same results are obtained.
26 of 31
Thematic analysis
A technique used when analysing qualitative data. Themes or categories are identified and then data is organised according to these themes.
27 of 31
Two-tailed test
Form of test used with a non-directional hypothesis.
28 of 31
Type I error
Occurs when a researcher rejects a null hypothesis that is true.
29 of 31
Type II error
Occurs when a researcher accepts a null hypothesis that was not true.
30 of 31
Refers to whether an observed effect is a genuine one.
