An Illustrated Guide to Data Literacy:

Welcome back to our comic series that explores a range of data literacy concepts. We follow Becky, who describes herself as a bit data-phobic, as she navigates tricky situations at her new job. She’ll learn to create effective charts, grasp statistical concepts, and confidently clean data for analysis with the help of her faithful desk plant Fern.

Today, Becky and Fern try to understand the difference between a percent change and percentage points.
