A solid grasp of the normal distribution plays a pivotal role in applying commonly used statistical techniques. Familiarity with additional distributions provides a foundation that will be useful in later courses. .1 Normal distribution
.2 Evaluating the normal distribution
.4 Part 1  Binomial distribution
.4 Part 2  Normal approximation to the Binomial distribution

Learn about the principles of inference that are used throughout much of statistics. .1 Variability in estimates
.2 Confidence intervals
.3 Hypothesis testing
.X Why do we use 0.05 as a significance level?

Inference for numerical data, such as for a single mean, the mean of paired data, or the difference of two means.
.1 Part 1  tdistribution
.1 Part 2  Inference for a mean
.2 Inference for paired data
.3 Difference of two independent means

Inference for proportions, goodness of fit, and 2way tables.
.1 + .2 Inference for proportions
.3 Testing for goodness of fit using chisquare
.4 Homogeneity and independence in twoway tables

Linear regression provides substantial insights that are most commonly understood through visual representations. This material provides an introduction to linear regression concepts, methods, and inference. 5.1 Line fitting, residuals, and correlation
5.2 Fitting a line by least squares regression
5.3 Types of outliers in linear regression
5.4 Inference for linear regression

Multiple and logistic regression are the most powerful methods introduced in OpenIntro Statistics. These methods are key elements of any statistician's toolkit. 6.1 Introduction to multiple regression
