Homework 3

Exploratory Data Analysis

For this homework you will need the following dataset: DATASET.

Before you proceed with your analyses you may want to see how your data “looks” like. This is called Exploratory Data Analysis. We do it for a number of reasons:

1. we want to assess normality

2. we want to rapidly compare samples

3. we want to check the variances of our variables

4. we want to see how our variables are related to each other

Using DATASET you are going to learn how to do this in R. And using this dataset you are also going to learn how to run some of the tests you can do to check for normality and homogeneity of variances.
