Project Assignment The purpose of this assignment is for you togain practice in applying the concepts and techniques we learned inclass. In order to complete the assignment, please do thefollowing:

1. find or create a data set containing values of at least oneinterval or ratio variable for at least one-hundred cases (n >=100); 1

2. provide basic descriptive statistics to summarize the centraltendency and variability of the data;

3. provide at least one table (see chapter 2: frequency,percentage, cumulative frequency, or cumulative percentage)summarizing the distribution of the data;

4. provide a graph (see chapter 3: histogram, line graph, ortime series graph) that illustrates a salient or important propertyor set of properties of the data;

5. calculate a confidence interval for the value of thevariable; and

6. conduct a hypothesis test using the data.

Write a short paper (~2-4 pages double spaced) summarizing yourwork. Be sure to clearly describe your findings, why you chose toanalyze the data as you did, and what your results mean. Forexample, if you chose to summarize the data’s variability using theinterquartile range (as opposed to the standard deviation), explainwhy you made this choice. Be sure to be as specific and clear aspossible about the rationale underlying your choices and about yourfindings.

1 Note that projects analyzing a nominal or ordinal variablewill receive no credit (i.e., a grade of zero).
