2. Introduction to Linear Data Analysis Using a collection of eight scatterplots, students determine graphs of lines or curves that might be appropriate models to describe bivariate data. Data that associates the length of a spring with the weight hung from the spring is used to find the linear regression line. Interpret the slope and the y-intercept of the line, and forecast other ordered pairs from the linear model. Technology: PowerPoint slideshow of scatter plots, Graphing calculator |
