In this video, learn how to plot categorical features to gain an understanding of relationships with target variables.
- [Instructor] We're going to pick up … right where we left off in the last lesson. … What we really want to understand … in this lesson is the relationship … between the different levels of our three … categorical variables and the survival rate. … This will tell us whether for instance, … women were more likely to survive than men. … This will give us an idea of which … features are useful and which are not. … So, we're going to use the same categorical plots … that we used back in lesson three, … and we're going to call that on the three features … that we want to explore. … This is the exact same code … that we walked through before, … but just as a reminder, … we're looping through our three categorical features. … So that's cabin indicator, sex, and embarked. … And then we're creating a new plot for each index … for the items on our list. … And then lastly, we're creating a categorical plot … where we're using the feature name, … plotting that against survived on the y axis, … using the Titanic data set, …
