25
What is a pilot study?
Smaller version of an actual investigation
26
What is the difference between a single-blind and a double-blind pilot study?
Single-blind = participants are unaware Double-blind = researcher and participants are unaware
27
What is a naturalistic and controlled observation?
Observations are done in the behaviours usual environment with the observer being concealed
28
What is a Covert and overt observations?
Covert = Participants are unaware they are being observed Overt = participants are aware they are being observed
29
What are participant and non-participant observations?
participant observations = researcher is part of the study non-participant = researcher is separate from the study
30
What is meant by inter-observer reliability?
multiple researchers record data in order to increase reliability of the findings
31
What is qualitative data?
Small amounts of data but in large detail
32
What is quantative data?
Large amounts of data in small detail
33
What is coding and quantitative data?
categorising the mass amount of data into meaningful units
34
What is Thematic analysis and qualitative data?
Turning qualitative data into quantitative by finding recurring themes
35
Define reliability
the consistency of results
36
How can a test-retest improve reliability?
by checking for the same results on a different occasion
37
What are the three types of validity?
Internal External Temporal
38
What is internal validity?
when the observed effects are due to the IV
39
What is a type of external validity?
Ecological validity- generalising findings from a study to other settings
40
What is Temporal validity?
whether or not findings from a particular study hold true over time
41
What is a paradigm?
a distinctive set of patterns
42
What is a paradigm shift?
It occurs when too much contradictory evidence exists against something
43
What is meant by falsifiability?
When findings are challenged and attempted to be proven false
44
What is replicability?
findings from a study must be repeatable if they are to be trusted
45
What are order effects?
the way in which questions are ordered can effect the answers
46
What are the four ethical guidelines outlined by the BPS?
Respect Integrity Social responsibility Maximise benefit and minimise harm
47
What are the three types of external validity?
Ecological Temporal Population
48
How do you asses external reliability?
test re-test
49
What is a covert observation?
When participants are unaware they are being observed
50
What is an overt observation?
The participants are aware that they are being observed
51
What is concurrent validity?
The level of agreement between two separate results taken at the same time
52
What is a longitudinal study?
Observing participants over a long period of time
53
What is meant by standard deviation?
The general spread of data after a study has been conducted
54
What is Empirical method?
Using scientific method which makes research more valid as it can be repeated
55
What is Objectivity?
Opposite of subjective, personal preference/beliefs are discarded in order to not hinder research
56
What is a null hypothesis?
when there is believed to be no difference between the experiments conditions
57
What is the alternative hypothesis?
States that there will be a relationship between two variables
58
What is a type 1 error?
When the null hypothesis is rejected and alternative accepted when it should have been the other way round.
59
What is a type 2 error?
When the alternative hypothesis is rejected and null hypothesis is accepted when it should have been the other way around
60
What is a one tailed test?
Used for when the hypothesis is directional
61
What is a two tailed test?
Used when the hypothesis is non-directional
62
What is an issue with primary data?
Could be expensive as well as needing time and effort
