Yes finally, I've been looking as well but have come up empty.
The case studies are both quite bad.
One gives no hypothesis
One gives no results
Both give not conclusions (or at least not full) 'My teacher said I did well'
Both fail to justify the significance of their secondary source.
There are plenty of ethical issues with the second (I'm sure you know filming someone in a park and uploading it isn't good). With the first i believe the questionnaire asks about drugs (and or alcohol) given the age of the sample this would be illegal and should notify authorities, I final issue with the first is- Why did he ask for their name in the first place? This causes lower validity as people are less truthful with their answers and are unlikely to trust the anonymous nature of the questionnaire.
I don't have the thing in front of me right now, but if you have any questions just DM me or something. Good luck on the 16th!
