Part One: Putting it All Together

This case requires that you present a research question and hypothesis, test it, and run a series of statistical tests to support your findings. The only mandatory statistical test that you have to perform is a MANOVA/MANCOVA.

Noise Testing in Classrooms

For the Noise-Testing Scores v4 data base you are to do the following tasks:

1. Present a Research Question and hypothesis. (Keep in mind that the research question and hypothesis directs the specific statistical testing and analysis needed to answer it.)
2. Perform the appropriate statistical tests to answer your hypothesis and research question.

• Be sure to perform the various statistical tests which are needed to support your findings for your original research question and allow you better interpret the results of your ANOVAs and MANOVAs. You  can also run Chi-Squares or correlations, descriptives, and t-Tests

3. Interpret all test results appropriately.  Report all statistics in appropriate format.

4. State your conclusions

U gandan Database

Repeat the same set of questions above for the Ugandan database. Ugandan dataset

For both datasets please be sure to only present results which are useful and have value (utility).

Part Two: Health Scare

The World Health Organization recently announced that the virus causing HBPS (Hemorrhagic Black Pox Syndrome) in Athens, Greece is a new pathogen that has never been seen before in humans.

Within 24 hours after arriving in Athens, you developed a standardized questionnaire to determine the likely source of the outbreak.  Within a couple of days, you interviewed 45 cases and 35 controls about their clinical symptoms and exposures.  During your interviews, you have discovered that a number of individuals just returned home about six weeks ago from a 1-month military mission abroad in Kinshasa, Zaire.  Based on preliminary analysis of your data, it appears that either travel history to Zaire and/or residing near the airport may be associated with HBPS.

What type of study design are you using to investigate the source of transmission?  Explain.

What surveillance methods would you use to find additional cases?

What is your hypothesis?

How would you select controls for this investigation?  Would you use matching?  Why or why not?

Analyze the exposure data below by calculating the appropriate measure of association and 95% confidence intervals for each exposure among the cases and unmatched controls.  Use stratification to separate the confounding effects of the other exposure.  Show your work in the calculating the measures of association.  For the 95% confidence intervals, you may find one of the confidence interval calculators above useful.

What does your analysis suggest regarding the likely source of exposure?  What further studies would you suggest to investigate the outbreak
