Use Binary Logistic Regression to describe the relationship between a set of predictors and a binary response. A binary response has two outcomes, such as pass and fail. You can also perform stepwise regression.
For example, marketers at a cereal company investigate the effectiveness of an ad campaign for a new cereal. The marketers can use binary logistic regression to determine whether people who saw the ad are more likely to buy the cereal.
If you have only one continuous predictor, you can use Simple Binary Logistic Regression.
