HLTH 200 Lecture Notes - Lecture 5: Inductive Reasoning, Statistical Hypothesis Testing, External Validity
Document Summary
The reality is that research is more circular and self-correcting. Fallacy an error in reasoning, usually (see slide) 4 types: construct validity quality of choices about the particular forms of the independent and dependent variables. Ex: asking people if they had smoked marijuana in the past 24 hours you should get much more info about their smoking habits. Ex: measuring for lead exposure but only doing it in iowa you should do a much more widespread study. Ex: applying knowledge from a study about communication in the 1930"s applied to today"s world with technology. Let"s say i didn"t choose a very representative group of students from the university. Use of a statistical test lacking sufficient power. Mistaking a trivial effect for support for the research hypothesis. Informed consent (was on the final last year) Misconception: it is just a form you fill out.
