I follow a MOOC and for the final exam, I have to provide some analysis of a dataset, and the opensource data they provide are so messy that I can not make any analysis. However they allow us to make an analysis as far as the dataset we work on is open source. So is there any one who could provide me with a tidy open source dataset please?
Some data sets will be tidy, others less so. Just a thought though, if the MOOC-provided data sets are "messy", it could be that tidying them is part of the final exam?
