Measures of SpreadIn the previous topic you explored important numerical measures of the center of a distribution. In this topic you will investigate similar numerical measures of a distribution’s variability. These measures will also lead you to dis¬cover another visual display (the .) and a very important technique (.) which will appear throughout the text.

Least Squares Regression IIn previous topics you studied scatterplots as visual displays of the relationship between two variables and the correlation coefficient as a numerical measure of the linear association between them. With this topic you will begin to investigate . as a formal mathematical model often used to describe the relationship between variables.

Least Squares Regression IIThis topic extends your study of least squares regression. You will examine the impact that a single observation can have on a regression analysis, learn how to use . to indicate when the linear relationship is not appropriate, and discover . of variables as a way to use regression even when the relationship between the variables is not linear.

Data and Variables II (bar graphs) for categorical variables. In this topic you will encounter a graphical display used for measurement variables. You will also continue to learn how to analyze the . of a set of data measuring a particular variable.

Measures of Center desirable to have a single numerical measure to summarize a certain aspect of a distribution. In this topic you will encounter some of the more common measures of the . of a distribution, investigate their properties, apply them to some genuine data, and expose some of their limitations.
