# Using R for Intro. Stats.

#### Robert W. Hayden

This page serves as an Table of Contents for "handouts" on
using R that I prepared for an online introductory statistics class. They
have been edited slightly to remove things wholly peculiar to my course.
The text I use is *Stats.: Modeling the World* (2^{nd} ed.)
by Bock, Velleman and De Veaux. Many of the data sets used below come from
this book or the accompanying ActivStats CD. Where needed, links to the
data set files are provided. While textbooks vary in order of topics, the
pages below should be used in the order listed as later pages assume R
skills from earlier pages. An exception is the scatterplots and
correlation page which can be used after the introductory page.

This introduction illustrates simple graphical
displays for a single variable along with a logarithmic transformation of
the data.

Inference for a single proportion.

Inference for a single mean.

Working with data tables.

Inference for two proportions

Inference for two means (independent samples)

Inference for two means (paired data)

Scatterplots and correlation

Transformations
