regression equations. In this packet you will be calculating different regression equations. (Each problem will tell you which regression equation to calculate) Your calculator will find the equation for you. After we find the equation to represent the points (data), we need to know how well the equation matches the data.

The students are then asked to use a computer or graphical calculator to carry out the linear regression of BAC on number of beers. The students are asked to interpret almost every number that the computer output gives. The students are then asked to make a residual plot and judge the appropriateness of the linear regression line.

Linear Regression dialogue box to run the multiple linear regression analysis. We now examine the output, including findings with regard to multicollinearity, whether the model should be trimmed (i.e., removing insignificant predictors), violation of homogeneity of variance and normality assumptions, and outliers and influential cases.

2-7 Linear Regression, Correlation, CausationDate_____ I can create and use a line of best fit both by hand (using two points) and using technology (linear or exponential). I can explain the meaning (using appropriate units) of the slope and y-intercept of a linear function in a real-world situation.

When a calculator or computer computes a regression line, it also gives the correlation coefficient. This is a number that is always between -1 and 1. It measures the degree to which the data is linear and whether the data is increasing or decreasing. The closer to 1 or -1 the correlation coefficient is, the more linear …
