Python for Machine Learning - The Complete Beginners Course - Frequency Distribution

The video tutorial explains how to analyze user ratings by plotting a histogram. It begins by describing the process of counting user ratings and then demonstrates how to write the necessary code to create a histogram using a data visualization library. Finally, it interprets the histogram, noting that the maximum rating was three and that approximately 120 users rated the movies around three stars.

What is the purpose of analyzing user ratings in this context?

• To find out how many users chose each rating
