Using Regression with the Alcohol Study and the Mode I Data Files

Using Regression with the Alcohol Study and the Mode I Data Files

Alcohol Study

Let's go back to the data files we used with the first two cases and see how we can use regression on them. We'll look at the Alcohol Consumption Study file first. The example output shown is from the Alcohol Study Practice file.

Suppose we want to know if any or all of the variables regarding drinking at dinner, bars and parties are good predictors of how many nights students go out.

Run a regression as follows:

DV: NIGHTS, IVs: DINNER, BARS and PARTIES

{Statistics - check off Descriptives}

Here is the output we need:

Answer the following questions based upon this output:

1. Drinking at which location/event is more likely to predict a higher number of nights a student goes out than the other locations/events?_______________________________

2. Drinking at which location/event is more likely to predict fewer nights out than the other locations/events? _________________________________________

Answers:

1. Drinking at which location/event is more likely to predict a higher number of nights a student goes out than the other locations/events? Bars

2. Drinking at which location/event is more likely to predict fewer nights out than the other location/events? Restaurants

Now let's look at how good the IVs VODKA, RUM and GIN are as predictors of how many nights students go out:

Run a regression as follows:

DV: NIGHTS

IVs: VODKA, RUM, GIN

{Statistics  check off Descriptives}

Here is the output we need:

Answer the following questions based upon this output:

1. Liking for which beverage is more likely to predict a higher number of nights out

than liking for the other beverages? _____________________________

2. Liking for which beverage is more likely to predict fewer nights out than liking for the other beverages? _____________________________

Answers:

1. Liking for which beverage is more likely to predict a higher number of nights out than liking for the other beverages? Vodka

2. Liking for which beverage is more likely to predict fewer nights out than liking for the other beverages? Rum
