SSCI 2910U Lecture 10: Week 10 Lecture Notes
Document Summary
Slide 2: the level at which the variable is measured determines the type of statistical analysis that must be performed. If there is a relationship between 2 variables, we can ask what is the strength with the 2 variables. Looking at: variables measured at an ordinal level (ex. Economic status), one category can be thought as better than the others. Slide 3: two collapsed ordinal level variables where there are fewer values (ex. Low and high), you may collect info on a variable that has 3 or 4 variables (ex. Low, medium, high and highest), collapse them by: high and highest as category #1 and low and medium is category #2. Gamma is not normally distributed (asymmetrical), the value of gamma will be the same regardless of which variable is taken as independent. Kendall"s tau-b and tau-c is used to analyze a bivariate relationship.
