Project 1:   Getting to know your data

Please feel free to impress by properly using recently learned statistical terminology when appropriate.

1.  Explain in detail what your data entail.  Include why you think the data were collected and how the data may be used by the party who collected them. Also, who is the target audience?

2.  Are the data from a sample or a population?  If they are a sample, what or who is the target population?

3.  List the quantitative and qualitive variables.

4.  Using Excel, make a graph or table of one or more of your qualitative variables.  You will likely have to group the data together into categories.

5.  Determne any patterns, trends or possible problems from your graph or chart from question

6.  Is there additoinal data that you would have collected?  If so, what and why?

Project 2 .

1. Choose three (3) of your quantitative variables in your data set and caculate the following:  Mean, Median, Mode, Range, Standard Deviation and IQR.

2. What are you hoping to learn that made you chooose those three variables?

3. Based on your answers to question 1, discuss the whether the variables are symmetric or skewed.

4. Use one of the methods discussed in class to determine if any of your variables contain outliers.  If so, list the outliers.

5. Based on your answers to questions 3 & 4, which measure of center best describes each variable.

6. Calculate the coefficient of variation for each variable to and rank them from least to greatest in terms of relative variability.  Is this what your expected-explain.
