In this course, you’ll learn several techniques for sampling data, such as random sampling and cluster sampling. You’ll also learn about discrete variables and random variables in the context of frequency distributions, and the different types of charts and graphs you might use to visualize frequency distributions.
As you learn about these concepts and how to use them for more robust data analysis, you’ll be working with a dataset about basketball players in the WNBA (Women’s National Basketball Association) that contains general information about players, along with their metrics for the 2016-2017 season.
Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. At the end of the course, you’ll complete a portfolio project that asks you to investigate Fandango Movie Ratings to determine if Fandango is inflating movie ratings on its site. This is an opportunity to learn to identify and overcome common setbacks in practical data analysis.
For this project, you’ll be a data journalist analyzing Fandango’s movie ratings to determine if there was any change after a 2015 analysis found evidence of bias. You’ll use R and statistics skills to compare movie ratings data from 2015 and 2016.
