How coronavirus charts can mislead us

Sarah Best

7th May 2020

This short video from Vox highlights how the collection and presentation of data (in this case about the coronavirus) may not tell us the full story about an issue.

For example, one of the aspects that is often covered in charts related to the coronavirus is the number of cases and this is often represented by a a line for each country. In most cases, the line for each country only refers to 'confirmed cases', indicating that could also be people who would also test positive for Covid-19 but they haven't been tested (and this could be due to things such as a lack of available testing kits for example). In other words, we need to know what the testing levels are for each country before being able to compare them accurately.

This video could be useful for the Research Methods unit (discussing issues such as validity and reliability, and types of data).
