bio386 R learning, apply, margin, t-test, p-value

I let students first reviewed R code 1-100 lines.

Then, student worked through 100-165.

I asked student to study examples of 'apply' and "margin". I then used a table on a paper to explain this. (I could do a youtube demo on this).

When we reached t-test and p-value, students have mis-conceptions. One student thought "as close to the one" means p-value should be close to 1 from the wikipedia entry on p-value.
