research methods Flashcards
what type of mwthod tells you if there is an association between 2 variables
correlational analysis
what experimental design makes participants take part in both conditions
repeated measures
what variable is manipulated in a lab experiment
the IV
what value tells you how strong a correlation is
correlation coefficient
what variable may not be able to be controlled and alter results
extraneous
what is it called when alternating the order participantscomplete the conditions
counterbalancing
what does counterbalancing do
reduce order effects
when a researcher lacks objectivity and may influence the views of participants
researcher bias
internal validity is when..
the study measures what it set out to
when the procedure and instructions are the same for all participants to reduce bias
standardised
how do you know you can rely on research
its repeated and similar resultd are foudn
ques may convey the researchers aim to the participant casuing them to change bhaviour
demand characteristics
a trial version of the research to check procedure accuracy and rectify errors
pilot study
variable measured
dependant
in a rep measures design in the 2nd condition the participant may improve, get bored or establish the aim
order efffects
a statement tat states exactly what they expect to happen
diredtional hypothesis
a type of experiment that makes use of pre existing differences between participnats
quasi experiment
what are the measures of central tendency
mean median mode—–ways of finding an average
an informal interview w out a script
unstructured interview
two variables being investigated in a correlation study
co variables
observing a staged event/ scenario is called a…
controlled observTION
a typed of closed question ta includes a scale from 1-5
likert scale
whats an open question
a question that allows/prompts one to elaborate, giving qualitative data
an experiment looking at differences between ppl,IV cannot be maipulated
Quasi
hidden way of observing participants where theyre unaware of them being watched is called a…
covert observation
watching and tallying every time you see a behaviour is..
event sampling
set behaviours to be tallied in an observation–they mustn’t be objective and not overlap
behavioural categories
a graph to display continuous data is called
a histogram
operationalising is where…
youre making sure variables are measurable and specific
