One of our topics this week involves looking at continuous distributions, and recognizing the "Normal distribution" bell curve when it appears. The text also covers other types of common distributions we see as well.

These have also been covered in The Lady Tasting Tea - and we've done a LOT of histograms in this class because of this very week. NOW you see why we take so much time in constructing those histograms - they can show us the distribution of a data set in an easy to recognize format.

For this week's Excel assignment, I'm going to let you use any of the data sets we have practiced with so far in class. They're all fair game from the gradesPreview the document data, to moviesPreview the document, basketball statsPreview the document, LMAS animalsPreview the document, etc.

Turn in an Excel spreadsheet with at least FOUR examples of distributions covered in the text this week. Show their histograms, and explain why you think they fit that particular distribution type. Also include the descriptive statistics that back up what you see from the graphs, and tell how they support that finding - because we can't always rely on visual analysis alone, of course!

Why not? See the link I have posted about The Datasaurus Dozen!
