SOC350H5 Lecture Notes - Lecture 6: Contingency Table, Logistic Regression, Scatter Plot
Document Summary
Non interval ratio data how do you describe categorical data. How do you build a model with dep variable is not interval ratio. When you deal with categorical data shapes what you can do with that data. You can describe single variable using mean/media. And also describe relationship between categorical (x/y) variable. Cross tabulation tells you how attributes of one variable intersect with attributes of another. All bivariate tables have rows (y variable) and columns (x variable) Cross tab variable indep is always column. Some relationship between the two shown in table. 24 countries are low in joiners and homicide 24 countries intersect there. If you produce a cross tab, be careful of where percent come from (divide value by total in column times 100) cell amount/total in column. Cross tab is like scatter plot you can eyeball distribution in a scatterplot. When you look at cross tab you can get some sense of variation.
