5. 4 1 KNR 497 Foundations Slide 4 Foundations of research  Hypotheses  A specific statement of prediction  Inductive vs. deductive research  Deductive has ‘em, inductive often doesn’t  Types  Alternative vs. null  One-tailed vs. two-tailed  Hypothetical-deductive model  2 mutually exclusive statements (null, alternative)  Tests designed to specify which can be rejected and which cannot 2 3

6. 1 KNR 497 Foundations Slide 5 Foundations of research  Types of data  Qualitative vs. quantitative  More a case of philosophical difference than numerical difference (in the better debates, at least)  The unit of analysis  Group vs. Individual vs. Artifact vs. Geographical unit vs. Social interaction  Hierarchical modeling 2

13. 1 KNR 497 Foundations Slide 12 Foundations of research  Fallacies  A variety of errors of either logic or premise strength that can result in weak arguments being formed.  Beyond the remit of this course, but very important nonetheless for good research papers  Examples:  Ecological fallacy: Mistaken conclusions about an individual based on analysis of group data  Exception fallacy: Reaching a group conclusion on the basis of exceptional cases (e.g., racism)
