5 Statistical inference is based on being able to determine the probability of getting a particular sample statistic from a population with a hypothesized parameter For example, we might ask how likely it is to get 55 heads on 100 flips of a fair coin If it seems unlikely, we might reject the notion that the coin we actually flipped is fair The probabilistic underpinnings of inference can be understood through the language of random variables In other words, we need random variables to bridge the gap between simple data analysis and inference CHAPTER
TwoVariable Data Analysis
IN THIS CHAPTER Summary: In the previous chapter we used exploratory data analysis to help us understand what a onevariable dataset was saying to us In this chapter we extend those ideas to consider the relationships between two variables that might, or might not, be related In this chapter, and in this course, we are primarily concerned with variables that have a linear relationship and, for the most part, leave other types of relationships to more advanced courses We will spend some time considering nonlinear relationships which, through some sort of transformation, can be analyzed as though the relationship was linear Finally, we ll consider a statistic that tells the proportion of variability in one variable that can be attributed to the linear relationship with another variable Key Ideas

In the previous chapter, we looked at several different ways to graph onevariable data By choosing from dotplots, stemplots, histograms, or boxplots, we were able to examine visually patterns in the data In this chapter, we consider techniques of data analysis for 93 94 U Step 4 Review the Knowledge You Need to Score High
twovariable (bivariate) data Specifically, our interest is whether or not two variables have a linear relationship and how changes in one variable can predict changes in the other variable example: For an AP Statistics class project, a statistics teacher had her students keep diaries of how many hours they studied before their midterm exam The following are the data for 15 of the students
