Rated A+ Introduction Section - Answer- -purpose of research -rationale for why research is important (based on previous knowledge) -research questions Methods Section - Answer- -How research is conducted -who participants were -what kind of info was collected -variables -design used -data used to confirm variables are reliable and valid Results section - Answer- -all information is reported -no interpretation -results and methods section should have matching headers Discussion Section - Answer- -author summarizes findings and interprets -future directions -limitations + implications Empirical Research - Answer- systematic intentional inquiry involving collection, analysis, and interpretation of data. anecdotal evidence - Answer- Personal stories about specific incidents and experiences 3 levels of scientific understanding - Answer- description, prediction, control description - Answer- what is going on (observation) prediction - Answer- -when will it happen? -correlation control - Answer- -experiment (functional relations) -can I make this happen internal validity - Answer- did the IV affect the DV not due to confounds external validity - Answer- results can be generalized Qualitative Research - Answer- -interviews and individualized accounts of events -does no seek to form correlation or functional relation group design - Answer- -large n, correlation -what factors are likely to cause outcome single subject - Answer- -small n, functional relations -IV, DV parametric research - Answer- value of IV is manipulated I.e. different doses of medication nonparametric research - Answer- independent variable is either present or not component analysis - Answer- treatment package evaluated by systematically removing one component of the intervention in order to determine if it is necessary Types of experimental questions - Answer- -demonstration -parametric -component -comparison threats to validity - Answer- -history -attrition -maturation -testing -instrumentation -diffusion -regression -selection bias `history - Answer- other events coincide with the intro to intervention -ex. medication change at intro of treatment maturation - Answer- developmental events or experiences that coincide with the introduction to the IV to produce a change testing - Answer- -change in Bx due to repeated exposure of experimental arrangement -practice effects demonstration - Answer- did the IV effect the DV comparison - Answer- (2 different IVs, 1 DV) will IV1 or IV2 affect the DV more parametric - Answer- (different levels of IV) how will different levels of IV affect DV component - Answer- will removing one element from IV change the DV instrumentation - Answer- -modification in measurement or dimension of measurement diffusion - Answer- -uncontrolled use of the treatment to control conditions or subjects -ex. practicing reading at home and then taught at school regression - Answer- -regression to the mean -changes occur bcs/ baseline data were not the natural state of events selection bias - Answer- -groups may have biased outcome even in absence of intervention -self-selection is when a subject is prone to greater improvement and more likely to participate in the strudy attrition - Answer- -loss of subjects over time -concerned with this in multiple baseline designs minimizing threats: measurement - Answer- -continuous measures -avoid short samples of Bx minimizing threats: stability - Answer- -make sure Bx is stable in the baseline condition -variability = problems with design minimizing threats: immediacy - Answer- -more immediate effect = more likely the chances IV produced it -look for change in level at intro of treatment minimizing threats: replications - Answer- -multiple cases -more cases impacted = IV produced change
