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?
