Some cool sources for data:
World Bank
Google Data Explorer (good for viewing various datasets, but need to go tot he source to download the data)
St Louis Federal Reserve Bank
US Census Fact Finder
US Bureau of Labor Statistics
US Bureau of Economic Analysis
NOAA and NWS for climate and weather data
FBI crime data explorer
CDC mortality data

Online statistics learning resources (a huge repository of resoruces)
Openstax (Basically very much like a proper textbook but online, seems easy to navigate, good basic examples)
Statlect (I really liked this one)

American Statistical Association statement on p-values
Common misinterpretations of the p-value and other statistical concepts

Guess the correlation game
Datasaurus dozen - shows how very different paired datasets can have the same scatterplot, and descriptive statistics

R statistical software:

You will need access to R statistical software. Here are instructions for getting R statistical software up and running on your computer. It should already be installed in all computer labs in Herak as well. If you find a computer where it is not installed, you can use these instructions to install it, or report it to me, and I will have IT install it. 

Here is a website where you can evaluate R code online from your web browser from any device:

Another option for having quick access to R (and this is useful for a smartphone) is SageCell at: This website can be used to evaluate commands from a variety of programming languages (including MATLAB and Python). Just select R from the language tab at the lower right of the textbox. If you are familiar with MATLAB, choose the option "Octave". Octave is basically an open source version of MATLAB and you can run MATLAB code using the Octave language option on SageCell.
