Review      Warner’s Chapter 12 and Chapter 2 of the Wagner course text and the media      program found in this week’s Learning Resources and consider the use of      dummy variables. Create      a research question using the General Social Survey dataset that can be      answered by multiple regression. Using the SPSS software, choose a      categorical variable to dummy code as one of your predictor variables. Estimate a multiple regression model that answers your research question. Post your response to the following: What      is your research question? Interpret      the coefficients for the model, specifically commenting on the dummy      variable. Run      diagnostics for the regression model. Does the model meet all of the      assumptions? Be sure and comment on what assumptions were not met and the      possible implications. Is there any possible remedy for one the assumption      violations?

Name an example of a real-world data set, not yet mentioned in the course, where you would typically expect to see a normal distribution. Be sure to describe what the labels would be for the horizontal and vertical axis of the display. Then explain why you would expect a normal distribution. What range of data values would you expect to represent 1 standard deviation from the mean? (15 points; 10 for your answer, 5 for response to others' comments.)This lesson asked you to investigate what it means for data to fall within 1, 2, and 3 standard deviations from the mean in a variety of normal distribution curves. Imagine that you hold a position on your city council and are in charge of creating new programs to benefit members of your community. In some cases, you must also decide which parts of the population are eligible for enrollment in a given program. How might the concept of standard deviations from the mean be interpreted in your decisions? For example, is it fair to make most programs only available to populations within 1 standard deviation from the mean? Can you imagine cases where you might want to create new programs for people who fall toward the extreme ends of the distribution? Give your opinion as well as some examples.
