A task which involves generating scatterplots and correlation coefficients using nutritional information from a McDonalds menu.
Worksheet and csv dataset.
Points of interest:
- Menu is from America leading to a discussion about how useful is it for use in UK
- High number of breakfast items and low number of burgers doesn’t reflect common perception of McD’s menu
- Sodium (ie salt) and calories have a strong correlation but this is a spurious relationship (salt has no calories) with portion size being a possible confounding variable
