Small-scale trial run of a method to identify & resolve any problems with the procedure
48
What is a Likert scale?
Measures attitudes using a statement to which P’s respond by choosing an option (Strongly agree to Strongly disagree)
49
What are closed questions?
Offers small number of explicitly stated alternative responses & no opportunity to expand on answers (quantitative data)
50
What are open questions?
Allows P’s to give full & detailed answers in their own words (qualitative data)
51
What is a structured interview?
Asks predominantly closed questions in a fixed order. Questions are scripted = standardised
52
What is a semi-structured interview?
Uses a fixed list of open & closed questions. Interviewer can introduce additional questions if required
53
What is an unstructured interview?
Starts with standard question but from there questions depend on the respondent’s answer. There may be a list of topics for the interviewer to cover
54
What is test-retest?
When you use same test twice
55
What is slit-half reliability?
When you compares 2 halves of a test
56
What is internal reliability?
The consistency of a measure gained through standardisation
57
What is external reliability?
Likely to get similar results if repeated in the same conditions

Extent to which a test measures what it claims to measure
59
What is external validity?
Extent to which the results of a study can be generalized to other people/situations
60
What is ecological validity?
Extent to which conclusions can be generalised to other situations

64
What is construct validity?
Extent to which a measurement tool actually measures the psychological concept being studied
65

Relationship between 2 variables such that an increase in one causes a decrease in another
68
What are extraneous variables?
Factor that can affect the outcome of an investigation other than those being tested
69
What are confounding variables?
Factor that confuses (confounds) the results because it acts the effect of the IV on the DV.
70
What is induction?
Uses observations to generate testable hypotheses which are developed into theories
71
What is deduction?
Develops hypotheses from theories, then tests the hypotheses with observations
72
What is falsification?
Ability to demonstrate that something is not the case
73
What is subjectivity?

Collect yourself
89

90
What are measures of central tendency?
Average score from a data set
91
What is the mode?
Measure of CT worked out as the most frequent score in a set of results (any data & CT for nominal data)
92
What is the median?
Measure of CT worked out as the middle score in the list when data is ranked. If 2 numbers are in the middle, they are added together & divided by 2 (used with nominal & ordinal data)
93
What is the mean?
Measure of CT worked out by adding up all the scores & diving it by the number of scores (used with interval data)
94
What is the range?
Measure of dispersion based on the biggest & smallest values in a data set ( + 1)
95
What is variance?
Measure of dispersion that calculates the average difference between each score. Bigger value = greater dispersion
96
What is standard deviation?
Measure of dispersion that calculates the average difference between each score & the mean. Bigger value = greater dispersion
97
What is a type 1 error?
Alternate hypotheses is accepted when in fact results are due to chance
98
What is a type 2 error?
Null hypotheses is accepted but results are not due chance therefore suggesting that there is no difference
99
What are the key ethics that one should consider?
Privacy Assent = continuously ask child if they want to participate Deception = P’s not deliberately misinformed about the aims Debrief = full explanation of aims & potential consequences of the study given to P’s after procedure Informed consent = enough info about a study to know whether to agree to participate Withdrawal = P’s should be aware that they can remove themselves & their data from the study Avoiding harm of participants = P’s not put at any greater physical/psychological risk Confidentiality = Individuals’ results & info kept safe & not be given to anyone outside study
