what is the correlation method
do variable x and y vary together and are they related in a systematic way
whats an example of a correlation method
do people who experience more stress have more headaches
how do correlation methods work
variables are measured but not manipulated
what is a disadvantage of correlation
does not imply causality because of the directionality problem
what do experiments involve
random assignment
manipulation of IV
measuring DV
what is the experimental effect
can evaluate treatment effectiveness by looking at differences between group or treatment conditions
what are 4 basic features of experimental design
investigator manipulates IV
participanys allocated condition by random assignment
researcher measures DV
what is the ABA experimental design
single case with an intial baseline stage- meaurement without intervention
manipulation stage
return to baseiline
what are analogue experiements
experiments not always possible in clinical psychology
examine related or similar behaviour in lab
what is epidemology
study of distribution of disorders in a population and possible correlates
what are three features of a disorder for epidemology
prevalence
incidenc
risk factprs
how are findings integrated from multiple studies
meta-analysis
what is meta analysis
identify relevant studies
compute effect size
what are qualitative methods
raw material for qualitative studies is ordinary language rather than quantifiable data
what is difference been quantitative and qualitative
requires response on seven point scale-data simple to process but limited in depth
requires open ended answer
