R and Basic Statistical Functions

The software R will be the statistical calculator we use for this course. Thus, we must begin by learning to work with data in R and to use a few basic R formulas and commands.

Warning

We have three pages that introduce the basic functions we need to use fluently to complete this course. Please do not disrespect these sections as the content will be used throughout the rest of the course and on quizzes and tests.

Data Frames

Our first help page is Data Frames.

R stores data in a data frame, so we must learn to load data sets into R as data frames and manipulate the data frame once we have it.

Descriptive Statistics

Our second help intro pages is Descriptives.

We must learn the basic commands for things like mean, median and standard deviation along with a few other basic commands like cat().

Visualizations

The final intro page is about Statistical Graphics.

We need to analyze histograms, box plots, scatter plots, density plots and normal QQ plots. This section will briefly describe the commands we need to produce these visualizations.
