| The "Quick Normal Calculator" is a javascript-based
tool that allows entry of z [or F(z)] values and gives back the
corresponding F(z) [z] values. This is convenient for the students,
but also it standardizes answers so it is easier to require a higher level
of accuracy than the case where every student can use any method they want
to find such values. Here's what the form looks like:
In actual use the form appears in a popup window.
To use this tool you need to do two things:
- Put the files NormalCalculator.html
and calculator.gif in the appropriate
directory of your course's website. (You can download those files by
right-clicking on the links shown.) NOTE: When you add
these files to your Mobius website you will be shown their addresses
(URLs). Please record these for use in the next step.
- Place the following code in your question text. Place the code
shown side-by-side in your source code.
a) The link to the calculator is done as follows:
<a onclick="window.open(this.href,this.target,'height=140,width=340')"
href="http://your server/your path/NormalCalculator.html"
target="Popup">
Follow this by the image tag:
<img border="0" align="right" title="Quick Normal/InvNormal Calculator [IMG:calculator.gif]"
alt="Quick Normal/InvNormal Calculator" src="http://your server/your path/calculator.gif" /></a>
NOTES: 1) The final </a> closes the link.
2) You may need to adjust the parameters height and width. Also
even when adjusted to your browser this popup may look different in
another browser.
If you didn't record the file addresses earlier, you can get the actual server/path string by visiting the website and
clicking on the file(s).
NOTE: Other tools (such as calculators for other probability
distributions) can be done this way.
