Q

Debriefing

A

Providing information about the true purpose of a study after the completion of the experiment

20
Q

Scales of measurement

A

Nominal - Categories have no rank (gender, nationality)

Ordinal - Categories do have rank (military rank, course grade)

Interval - Steps on scale have actual meaning (celcius, IQ scores)

Ratio - Scale has a true zero (age, height)

21
Q

Discrete variables

A

Consist of whole number units or categories and are made up of chunks or units that are detached and distinct from one another

22
Q

Continuous variables

A

Fall along a continuum and allow functional amounts

23
Q

Self-report measures

A

Questionnaires or interviews that measure how people report their actions, thoughts or feelings

24
Q

Reactivity

A

A possible reaction by subjects in which they act unnaturally because they know they are being observed

25
Types of reliability
Test-retest - Assesses the degree of relationship between scores on the same test on two different occasions Alternate forms - Different but equivalent Split-form - Comparing two halves of a test Interrater - When there is consistency between judges
26
Types of validity
Face - Assesses the face value and what the test measures Construct - How well does the measure address the construct in question Content - How well does the measure address the content of the construct Criterion - How well does the measure predict some criterion either in the present (concurrence validity) or in the future (predictive validity)
27
Options when using observation
Undisguised Nonparticipant Participant Disguised
28
Narrative records
Full narrative descriptions of a subject's behaviour
29
Qualitive methods
``` Case study method Archival method Interview Focus group interview Field studies Action research ```
30
Causality
The assumption that a correlation indicates a causal relationship between two variables
31
Restrictive range
A variable that is truncated and has limited variability
32
Regression analysis
A procedure that allows us to predict an individual's score on one variable based on knowing one or more variables
33
Probability
The study of the likelihood and uncertainty
34
Null hypothesis
Predicts no difference exists between the groups being compared
35
Alternative hypothesis
The hypothesis that the researcher wants to support, predicts a significant difference between the groups being compared
36
One-tailed hypothesis
An alternate hypothesis in which the researcher predicts the direction of the expected difference between the groups
37
Two-tailed hypothesis
An alternate hypothesis in which the researcher that the groups being compared differ but does not predict the direction of the difference
38
Type I error
An error in hypothesis testing in which the null hypothesis is rejected when it is true
39
Type II error
An error in hypothesis testing in which there is a failure to reject the null hypothesis when it is false
40
Inferential statistic tests
Parametric tests - Involves making assumptions about estimates of population characteristics or parameters eg. z or t test Nonparametric tests - Does not involve the use of population parameters and the mean and standard deviation are not needed eg. Chi-square or Wilcoxon test
41
Confound
An uncontrolled extraneous variable or flaw in an experiment
42
Internal and external validity
The extent to which the results can be attributed to the manipulation of the independent variable than to some confounding variables The extent in which the results can be generalised
43
Threats to internal validity (10)
``` Nonequivalent control group History effect Maturation effect Testing effect Regression to the mean Instrumentation effect Mortality or attribution Diffusion of treatment Experimenter and subject effects Floor and ceiling effects ```
44
Effect size & Cohen's d
The proportion of variance in the dependent variable that is accounted for by the manipulation of the independent variable An inferential statistic for measuring effect size
45
Order effects
A problem for within-subjects designs in which the order of the conditions has an effect on the dependent variable
46
Counterbalancing
A mechanism for controlling order effects
