Histogram Calculator - A Java Applet

My statistics professor used to say: "drawing histograms is a good skill to have."

Drawing histograms is not hard, but it is tedious if you have a large data set and are doing it by hand. For this reason, I coded this histogram calculator.

There are quite a few things that can be said about histograms, however, to use this calculator all you need to know is that if you enter a set of numbers (separated by spaces, tabs, or returns) and click the "Draw Histogram" button you will see the rendition of the data set into a histogram and a quick summary of the data, e.g., the average, standard deviation, and such.

Notes:

1. One of the main things a histogram allows you to do is to check if your data set is a good fit for a Normal model. You do this by super imposing a plot of a Normal curve: N(0, 1).
   
   My Histogram Calculator super imposes the normal curve on top of the histogram.
   
   There are formal methods to asses "fit" of your data to a Normal model, however, these methods are our of scope on this page.
   
   
2. To use: enter a set of data and click the "Draw Histogram" button.
   
   
3. The Applet needs the latest Java plug-in. I.e. It is not 1.0 compliant.
   
   Now, why would I require you to download a plug-in to use my application? I started coding and compiling J2SE 1.5 and now I don't feel like porting it back to an older version :)
