Analyzing the Relationship Between Two Variables Bivariate Analysis Analyzing the Relationship Between Two Variables

Types of Bivariate Analysis New Terms: Independent Variable; Dependent Variable Remember your variable types: Nominal; Ordinal; Interval To analyze the relationship between 2 variables, we will define several possibilities: Nominal-Nominal or Ordinal Nominal-Interval Interval-Interval

Bivariate Analysis, for each combination Nominal-Interval: Difference of means Nominal-Nominal: Cross Tabulation Interval-Interval: Correlation and Regression Analysis Surprise! You’ve already been doing some of this…..and have seen these procedures in Simon.

More visuals: Difference of Means

Nominal-Interval Bivariate Analysis: Mean Difference Does the average number of persons in a household differ by neighborhood?

Nominal-Nominal Bivariate Analysis: Cross Tabulation Occupational Distributions by Ward, 1905:

Interval –Interval Bivariate Analysis: Regression and Correlation Does the size a building determine it property value?
