In the last lesson, we learned how to create bar plots in Python to compare the average user rating a movie received from four movie review sites. We also learned how to create scatter plots to explore how ratings on one site compared with ratings on another site. We ended the lesson with the observations that user ratings from Metacritic and Rotten Tomatoes spanned a larger range (1.0 to 5.0), while those from Fandango and IMDB typically spanned a smaller range (2.5 to 5 and 2 to 5 respectively).
In this lesson, we'll learn how to visualize the distributions of user ratings using histograms and box plots. As we do that, we'll continue working on our own investigation of whether Fandango’s movie review ratings might be biased, based on the investigation conducted by FiveThirtyEight.
As with every lesson at Dataquest, you'll be given an opportunity to practice each concept using our code editor with built-in answer checking to ensure that you've mastered a concept before moving on to this next.
