Class Assignment 1  (8/20/02):
    Create your own Home Page

Class Assignment 2  (8/22/02):

Class Assignment 3  (9/5/02):
Explore a new data set with histograms
    -    Start with data in spreadsheet StudyHabitsIndexData.xls
            *    Number attempt to quantify "quality of study habits
            *    Measured for 18 females and 20 males
            *    How do the populations compare???
    -    Address this question by an Excel analysis based on histograms
            *    Just try something, then we compare and discuss
    -    Display your results and conclusions on a new web page
            *    Linked to your home page
            *    You select format and style of presentation
            *    But insert some graphics generated by Excel
    -    Some graphics ideas to consider:
            *    Look at two separate histos, or some "combined version"???
            *    I.e. single graphic showing both "together" (experiment with Excel)
            *    Answers depend on binwidth, how to effectively display several?
    -    Some additional questions (answer on your web page, w/ discussion):
            *    Which group "looks better on average"?
            *    Can you "quantify this idea"?  (e.g. give numerical measures)
            *    Which group "looks more spread" (i.e. has "greater variation")
            *    Quantify this idea by using the STDEV function in Excel
            *    Suppose you are an employer who must hire
                     somebody from one of the two groups.
                     Would you hire a female or a male, if:
                        +    You are forced to choose "at random"
                        +    You can carefully select from a large group of each type
                     Why?
