This project will give you the opportunity to apply the analysis methods of descriptive statistics to sets of data.

You will also collect data, analyze data, and write a project report.

Complete the following :

1. In paragraph form, describe your topic. You may choose any topic you wish as long as it involves quantitative data ( numbers ) of some kind. Identify the relevant population relating to your topic. Next, obtain data in order to address your question of interest. Collect two samples related to your question of interest where the sample size ( n ) is 40 or more for each sample. One sample should represent one characteristic of your population, while the other sample represents a corresponding aspect, however, the data you collect for each sample must measure the same variable. For example, ask 40 men and 40 women how much they weigh, or ask 40 smokers and 40 nonsmokers how many minutes per week they exercise. The purpose of this is to determine whether the values vary between the two different groups in your population. You must obtain your data by conducting a survey. In paragraph form, describe how you obtained your data, including the phrasing of the question you asked and how you conducted your poll ( e.g. asked friends, family, coworkers, went to a mall, chat rooms, etc. ). Finally, include a list of the values for both samples in your project report.
2. a. Provide a list of your original data. This should be a TWO lists of at least 40 numbers each.
   FOR BOTH SAMPLES
   b. Calculate the mean, median, and mode using the methods described in Chapter 3-2.
   c. Create a frequency distribution table. Include relative frequencies in your tables.
   d. Calculate the range, then use the range rule of thumb to estimate the standard deviation (pg. 98).
   e. Calculate the standard deviation and the variance from the original data.
   Use either Formula 3-4 or 3-5 for the standard deviation calculation.
   f. Calculate the 5 number summary
3. Create a boxplot for the two samples. Plot both boxes against the same axis for comparison. See the boxplot on page 122 for an example.
4. Assume that the data is bell-shaped. For both samples, use the mean and standard deviation to find the limits for 68%, 95%, and 99.7% of the data. ( Hint : Empirical Rule page 100 )
5. In paragraph form, describe what you have found and write your conclusions based on your sample and the analyses you have performed.

Your report should be typed and neatly organized . You may perform your analysis using a computer, or you may do it by hand. In either case, all work must be shown, and it must be neat and organized.
