 hypotheses specific propositions that follow logically from a theory deduction process of reasoning from a general proposition to specific implications of that theory (deriving from existing theory) induction abstracting a hypothesis from a collection of facts (collecting info to allow you to form a hypothesis) falsifiable potential to be found false quasi-experimental research use when not able to vary the independent variable study effects of some variable or event that naturally occurs identity each number has a particular meaning magnitude numbers have an inherent order from smaller to larger true zero zero represents a zero level of the variable being measured nomaial scales lowest level of measurment least match their number system naming scales, only property is identity chi square categorical data ordinal scales measure variables in order of magnitude do not tell anything about difference in categories ordered data interval scales properties of ordinal scales + equal intervals b/w consecutive values on scales come close to matching number system but no true zero score data ratio scale properties of identiy, magnitude, and equal intervals + true zero point score data scale attenuation effects restricting range of scale ceiling effect=no room to show change toward higher scores floor effect= restricted lower range chi square assess relationship b/w 2 nomial variables common causal variables cause both predictor and outcome, thus produce correlation b/w them spurious relationship=produces and 'explains away' relationship b/w predictor and outcome variables longitutdal research path anaylsis= multiple regression to assess the relationships among number of measured variables
