week 1 Flashcards
What is an instrument
a way of collecting data. This could be a questionnaire, individual interviews, focus group interviews, observation, checklists, experiment
What is survey
The instrument and process of collecting, analysing, interpreting the data
What is a scale
A set of items that measure different aspects of a single construct. Sometimes called the measure
What is a subscale
Sub-set of items measuring different aspects of the thing we are trying to measure overall
What is an item
a question along with the rating scale to answer it
What is a self-report
A measure relying on participants reporting what they did/do/will do
What is observation
a behaviour that researchers observe, then put into a category
What data can we get from surveys
Attitudes, Behaviours and behavioural intentions, demographic information, evaluation and traits and states
What types of surveys are they
Exploratory surveys: investigating new phenomena
Descriptive surveys: when, where and with whom a phenomenon occurs
Explanatory/predictive surveys: aim to explain why phenomena occur
Experiments vs surveys
In experiments, the focus is on establishing causal relationships
Surveys can examine relationships between variable, but no manipulation involved
What was Anderson and Dill study
Used both survey and experiments
survey. Measures: self- report video game use, trait aggression, delinquency and recorded participants
study 2 experiment: between-subject design. 2 (violent, non- violent video games) x2 (high, low trait irritability) x2 ( male, female). Participant assigned to one of 8 conditions, measure aggressive behaviour .
Playing violent video games significantly predicted aggressive behaviour
What is factor analysis
The idea of factor analysis is that similar items will group together
Exploratory factor: analysis is a first pass at this
Confirmatory factor: analysis is a check on the exploratory model
