# Homework 2: Visualization Scott Alberts (modified Scott Thatcher) September 5, 2018

Introduction Read Chapter 3 (http://r4ds.had.co.nz/data-visualisation.html) of our text and complete Lab 2 on visualization before you start this assignment. You should use RStudio with ggplots for this assignment about Tasmanian Abalone (abalone are yummy marine snails).

The data set abalone_clean.csv contains measurements of 10 variables (1 categorical, 1 integer and 8 numeric) on n = 4177 snails. Someone in Tasmania collected these 4,000 delicious measurements:

Categorical: sex (M, F, I), (I=Indeterminate sex. I have no idea how you tell the sex of an abalone, and often, neither could the abalone scientist.) Integer: rings (in general, an abalone gets a new ring each year, sort of like a tree) Numeric: length , diameter , height , whole.weight , shucked.weight , viscera.weight , shell.weight .

Units for numerical variables are mm and g, as appropriate.

You can find the cleaned data set along with this homework set on Blackboard. The original is available from the UCI Machine Learning Repository (https://archive.ics.uci.edu/ml/datasets/Abalone), but you shouldn’t have to use it.

Assignment Explore these questions using R. Do NOT do any “real” statistics, like t-tests or ANOVA. Do make relevant and awesome charts, tables, and graphs. You should use R markdown to create a homework submission that shows your code and comments for each part below.
