Easy -1.8 This is a straightforward recall question about the Large Data Set requiring no mathematical calculation or problem-solving. Students simply need to state two basic limitations (e.g., sample vs population, missing years, or vehicle type coverage) that they should have learned when studying the dataset. It tests data literacy rather than mathematical technique.
A reporter is writing an article on the CO₂ emissions from vehicles using the Large Data Set.
The reporter claims that the Large Data Set shows that the CO₂ emissions from all vehicles in the UK have declined every year from 2002 to 2016.
Using your knowledge of the Large Data Set, give two reasons why this claim is invalid.
