Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

A professor has a class with four recitation sections. Each section has 7 students (rare, but there are
exactly the same number in each class...how convenient for our purposes, yes?). At first glance, the
professor has no reason to assume that these exam scores from the first test would not be
independent and normally distributed with equal variance. However, the question is whether or not
the section choice (different TAS and different days of the week) has any relationship with how
students performed on the test.
