Some quantitative variables can be treated only as ranks; they have a natural order, but these values are not strictly measured. Examples are: 1) age group (taking the values child, teen, adult, senior), and 2) Likert Scale data (responses such as strongly agree, agree, neutral, disagree, strongly disagree).

In Chapter 3, we learned how to analyze relationships between two quantitative variables that showed a linear pattern. When two-variable data show a curved relationship, we must develop new techniques for finding an appropriate model. This section describes several simple transformations of data that can straighten a nonlinear pattern.

Correlation examines relationships between two quantitative variables (interval/ratio data) Scatterplot shows the relationship visually. Use it to check for pattern in data (hi/hi or hi/lo?) If linear pattern, can us Pearson’s r coefficient. Use it to look for strength (scatteredness) Pay attention to outliers (p. 215/216 examples)

Proxy variables can either be close or remote/distant. Larger is the number of proxy variables, and more distant/remote they are; less genuine become the results of the given quantitative assessment. Fixing the Sample Size: In any quantitative study, based on sampling, correct sample size is a must to have a specified degree of precision.

In this case the BMI, blood pressure, cholesterol level and so forth are explanatory variables and the life expectancy is the response variable. Scatterplot: A scatterplot shows the relationship between two quantitative variables measured on the same individuals. Each individual is one dot. If there is an explanatory variable put it on the x-axis.
