Remember also that we would like you to include a brief description of your ideas for a final project in your next journal.
The SAT article, SAT data, chance news article, and cookies data were each given a maximum of 5 points. The Alzheimer's article was worth 4 points, and extra comments were given up to 4 points. If you suspect any part of your journal was not read, please let us know.
Joseph wanted to mention from reading the journals:
2) someone asked: "how safe ae condoms?" He had an argument with a born-again Christian, and now he's worried.
3) A few people were confusing correlation coeffients with probability. A correlation of 0.5 does not mean that the pattern was just as likely to appear by chance: 0.5 is actually a good correlation. Instead, you would expect a correlation of 0 if there was no relation between the variables and just chance was at work.
