Instructions for Conducting Multiple Linear Regression Analysis in SPSS. Multiple linear regression analysis is used to examine the relationship between two or more independent variables and one dependent variable. The independent variables can be measured at any level (i.e., nominal, ordinal, interval, or ratio).

Students will be able to use 2 data lists, plot the data, not on graph paper but on the TI-83 graphing calculator. Students will be able to calculate and then graph a line of regression on the TI-83 calculator based on the data given, then make predictions about what might happen in the future using the line of regression.

Plot a graph of the average acceleration (y axis) vs. sin(q). Use your calculator, Graphical Analysis, or graph paper. Carry the horizontal axis out to sin(q) = 1 (one) to leave room for extrapolation. Draw a best-fit line by hand or use the linear-regression feature of your calculator or Graphical Analysis and determine the slope.

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 …
