When does an extraneous variable become a confound?
When it systematically varies both the IV and the DV
35
What kind of true experimental designs are there?

36
What kind of quasi experimental designs are there?
Pre-experimental - Single-group post-test only (-) - Post-test only non-equivalent groups (-) - Pre-test post-test single group design (-) - Pre-test post-test non-equivalent group Interrupted time series (repeated measures pre and post intervention) Regression-discontinuity (below/ above set criterion value into different groups)
37
What are types of single-case experiments?
[A = baseline phase; B = intervention phase] A-B designs (similar to interrupted time series) A-B-A designs A-B-A-B designs Multiple baseline designs - Across settings - Across behaviours - Across participants
38
Why do non-experimental fixed designs exist?
Some things cannot be modified (e.g., age), should not be modified (e.g., smoking), are not feasible to modify (e.g., placement in school)
39
What are types of non-experimental fixed designs?
Descriptive Explanatory Predictive
40
What are the three types of time-dimensions?
Cross-sectional (1 point) Longitudinal (2+ points) - Panel designs (same participants) - Trend designs (different participants) Retrospective (simulate longitudinal)
41
What are three common design problems that lead to rejection from AMJ?
Mismatch between research question and design (e.g., cross-sectional design for causal RQ, wrong sampling) Measurement and operationalisation (wrong adaptation of pre-existing measures, common method variance) Incomplete model (proper use of control variables, mediators operationalised)
42
What are the three conditions control variables should meet for being included in a study?
1. Strong expectation that it's correlated with DV 2. Strong expectation that it's related with IV 3. Logical reason why it's not a more central variable
43
What do Spencer et al. thinking about measurement-of-mediation designs?
Nah g
44
When should one use a measurement-of-mediation design?
Mediator hard to manipulate but easy to measure
45
When should one use a moderation-of-process design?
Mediator easy to manipulate but hard to measure
46
When should one use a experimental-causal-chain design?
Mediator easy to manipulate and easy to measure
47
What is a census?
When u survey a whole entire population
48
What types of probability sampling are there? (5)
Simple random sampling (e.g., lottery) Systematic sampling (e.g., every 5th name) Stratified random sampling (e.g., from subgroups) - can be (dis)proportionate Cluster sampling (when population dispersed and large) Multi-stage sampling (cluster sampling, can be stratified; e.g., school - class - child sample)
49
What kind of non-probability samples are there? (10)
Quota sampling (from various population elements) Dimensional sampling (kinda quota sample; include important survey dimension in sampling) Convenience sampling (near & convenient participants) Purposive sampling (specific sample; used in grounded theory) Snowball sampling (participants find new ones) Time sampling (across time; use specific space at specific time) Heterogeneous sampling (wide varying on value) Homogeneous sampling (little varying on value) Extreme case sampling (extreme values) Rare element sampling (low frequency in population)
50
What is a sociometric scale?
Describes relationship between individuals in a group
51
How can a time frame be provided in questionnaire questions? (5)
Bounded recall (since last...) Restricted recall period (in last 3 months) Average (how many on average) Marks (since beginning of school year) Cues (when u won...)
52
What are the three main observational method types?
Participant observation (flexible, qualitative) Structured observation (fixed, quantitative) Unobtrusive observation (non-participatory role; can be (un)structured)
53
What are four advantages of observation?
Directness Triangulation (help complement other info) No social desirability effect Lack of artificiality -> ecological validity
54
What are three disadvantages of observation?
Reactivity (if observer affects situation) Logical problem (behaviour measured or not?) Time consuming (less if structured)
55
What's the dichotomy of observation as a method?
Formal observations (structured, direction; pre-specified elements) -> reliability, validity Informal observations (more freedom) -> complete, complex data
56
For which situations is participant observation suited?
Small groups Short events Frequent events Accessible events Enough time U wanna find out what's going on
57
What does participant observation entail?
Becoming member of observed group to share "symbolic" world, habits, norms, etc.
58
What are participant observation roles?
Complete participant (observer doesn't share observer status) Participant-as-observer (participating & observing) Marginal participant (less participation; e.g., bus passenger) Observer-as-participant (no participating but consensual observing)
59
What are the five main steps of analytic induction?
1. Rough definition 2. Initial hypothesis 3. Study situation in context of hypotheses 4. Edit hypotheses or definition 5. Repeat
60
What observational biases come with participant observation?
Selective attention (even out attention) Selective encoding (subconscious) Selective memory (write shit up) Interpersonal factors (biases)
61
What are two truths regarding mono method bias Spector names?
Measurement affects data Same method and same bias -> correlation inflated
62
What are five sources thought to be central to mono method bias?
Social desirability Negative affectivity Acquiescence Illusory correlations Halo bias
63
How can u deal with mono method bias?
Rethink - is it actually there? Different sources to measure IV and DV Separate IV and DV measurement (temporally, psychologically w cover story, proximally in different conditions)
64
What two viewpoints are there about real-world research?
Evaluation viewpoint (understand, communicate) Change viewpoint (suggest how to change shit)
65
What are the three types of gap spotting?
Confusion spotting (competing explanations) Neglect spotting (under-researched) Application spotting (extending existing literature)
66
What are the three key ideas of abduction?
1. Explaining patterns of data, build hypothesis 2. Entertaining multiple hypotheses (comparative theory evaluation) 3. Inference to best explanation (similar to grounded theory) - best explanation given evidence
67
What are criteria for theory evaluation? (5)
Fruitfulness, parsimony, scope, progressiveness, consistency
68
What are three famous flexible design research strategies?
Case study Ethnographic study Grounded theory study
69
What components of a study should be decided on before and after RQ?
Before: Purpose, conceptual framework After: methods, sampling
70
What's the ecological fallacy?
Making inferences about individuals from aggregate data
71
Validity =
accuracy
72
Reliability =
consistency
73
What are the two ways in which lab experiments may lack realism?
Experimental realism - situation not: realistic, involves & impacts participants Mundane realism - situation not realistic in real world
74
What are two general types of bias specific to experiments?
Demand characteristics (do what u think u should) Expectancy effects (experimenters see what they wanna)
