Negative Value in Covid-19 Dataset I am currently practicing my data visualization skills with ourworldindata dataset. I noticed there is a negative value of new_cases in Benin country. Out of curiosity, what does that mean? I mean, why would the new_cases has a negative value?
Here is where the negative value is found.
Looks like that number is calculated from the total_cases column. Value = &quot;total_cases from day before&quot; - &quot;total_cases of that day&quot;. In this case: -209 is 130 - 339. Not sure why that number would decrease, but could be they changed the way they count, or just an error in the data.
