Missing description of data in sample.csv #569

Open tobyhodges opened 1 year ago

tobyhodges commented 1 year ago

We received a question from a learner who was confused by the contents of the example sample.csv file used in this lesson:

"In particular, I would like to know to what type of measure the columns Aneurisms_* refer to. In addition, what are the Q1/2/3/4 suffix?"

The lesson describes the data in the file as "the results of an (not real) experiment, looking at the number of aneurysms that formed in the eyes of patients who undertook 3 different treatments" so I am guessing that the numbers in each Aneurisms_* column are meant to represent the number of aneurisms in each quarter (three months) after treatment began.

Can anyone with knowledge of teh history of the lesson correct/confirm this, and maybe put in a pull request to add this extra context to the lesson?
