POLC78H3 Lecture Notes - Lecture 2: Null Hypothesis, Church Attendance, Statistical Hypothesis Testing
Document Summary
1st hypotheses- trying to explain unemployment rates in country, and they are using literacy rates to explain it- literacy rate-ind variable. 2nd hypotheses-trying to explain individual political knowledge and using level of religiousity. Ind variables could be in the category of something we would never try to explain. What is an ind variable depends on political scientists choice. Older catholics-------oppositions- dep var- oppose abortion, ind age, regular church attendance(whether or not you show to church regularly), religion(catholics) so 3 ind variables here. Tautological- relationships that are true by definition; often a set of assumptions is that one variable can not perfectly affect another variable. Existing theory eg homosexuality article for the weak that you cant be homosexual bcz it will affect performance. For every hypotheses, there is a null hypotheses. If hypotheses says there is a positive relationship then the null hypothesis says that there is no relationship.
