Building a Model on the Unprepared Data

  1. To build a model on the unprepared data, from the menus choose:

    Analyze > General Linear Model > Univariate...

  2. Select Sales in thousands [sales] as the dependent variable.
  3. Select Vehicle type [type] as a fixed factor.
  4. Select 4-year resale value [resale] through Fuel efficiency [mpg] as covariates.
  5. Click Save.

The default GLM Univariate output includes the between-subjects effects, which is an analysis of variance table. Each term in the model, plus the model as a whole, is tested for its ability to account for variation in the dependent variable. Note that variable labels are not displayed in this table.

The predictors show varying levels of significance; those with significance values less than 0.05 are typically considered useful to the model.
