Online Statistics Courses. What is Statistics?
Statistics is an academic discipline concerned with the collection, graphic representation, and analysis of data taken from specific population surveys. College statistics programs often focus on three subsections of statistical study: applied, theoretical, and mathematical statistics. Applied statistics courses consolidate the study of descriptive and inferential statistics, which uses results from probability studies to explain clear numeric correlations in data as well as the more random results. On-campus and online statistics courses that discuss theoretical statistics use logic and probability theory to explain why data sets yield certain results while mathematical statistics are concerned with fundamentally altering experiment designs to create different probability data.

Linear regression analysis. An important part of statistical analysis is being able to look at graphical representation of data, extract meaning and make comments about it, particularly related to the context.
Graph interpretation is a difficult skill to teach as there is no clear algorithm, such as mathematics teachers are used to teaching, and the answers are far from clear-cut. This post is about the challenges of teaching scatterplot interpretation, with some suggestions. When undertaking an investigation of bivariate measurement data, a scatterplot is the graph to use. On a scatterplot we can see what shape the data seems to have, what direction the relationship goes in, how close the points are to the line, if there are clear groups and if there are unusual observations. The problem is that when you know what to look for, spurious effects don’t get in the way, but when you don’t know what to look for, you don’t know what is spurious.
So how do we teach this? The following uses the framework provided by R. Assistments. Resources for AP Statistics, Intro to Statistics, and R. Data Finder. Getting and Using Data. Statistics in Sports: Sports Data Resources. Derby lines, futures wagers, betting tips, news and results.
