Project 2 Task 2.04 Assumption Confusion #59

Closed shawnwiggins closed 6 months ago

shawnwiggins commented 9 months ago

A few students from one section of MATH 108 expressed confusion about the assumption in Task 2.04 which states:

Assume averages and totals are taken over the total precipitation sums for each year.

This is causing some confusion about whether or not the total number of drought and non-drought years is important to consider for using test statistics 1 and 2. In other words, should 1 and 2 be considered correct answers?

@amclanahan, do you have any public thoughts on this?

Consider this in relation to Task 2.05. Permutation tests can handle a mismatch of the sizes for each group, but is the ratio of drought to non-drought years too extreme?
