Statistics in GeoGebra 4.0

This is probably GeoGebra Week since I have written a lot about GeoGebra. Anyways, here’s another one.

This is a very helpful tutorial on how to create histogram and boxplot using GeoGebra. Statistics is one of the greatest improvements in GeoGebra 4.0.

GeoGebra Advanced Tutorial 11 – Embedding GeoGebra Applet in WordPress Blogs using the Media Library

Note: This tutorial is for hosted WordPress blogs.  As of this writing, GeoGebra applets cannot still be embedded in WordPress.com blogs.
Instructions
1.) Be sure that you have a WordPress iframe plugin. I use Embed Iframe in embedding GeoGebra applets so I recommend that you use it since I don’t know if the code is similar using other plugins.
2.) Export Your GeoGebra Worksheet as Dynamic HTML. Be sure to take note of the width and the height of your applet. These can found in your Advanced tab of the File Export dialog box.
3.) (Optional): Edit your HTML file using a Text Editor (see how below). Although this is optional, I recommend that you do this.
4.) Go the the Library in the Media panel your WordPress Dashboard and upload your dynamic HTML file.
5.) Once the file is uploaded, click on the Library link again in the media panel to display all the uploaded files and click the file name link of your GeoGebra html file. This will display the Edit Media page. » Read more

GeoGebra Advanced Tutorial 10 – Embedding GeoGebra Applets in a WordPress blog

Micky Bullock has written a tutorial on how to embed a GeoGebra applet on WordPress blogs using iframe in the Secret Garden of Maths, so it is pointless for me to repeat the tutorial. Below, however, are some of the problems I encountered when I followed the tutorial and the solutions I did to display the applet. It is likely that you will encounter the same problem, so you may want to bookmark this post.

Commonly Encountered Problems

Problem 1: Applet does not display.
Solution: Update Java Runtime Environment.

Problem 2: Scrollbars appears on my applet.
Solution: Do one or more of the following:
a.) Be sure that your applet is smaller than the frame where you will place the applet.
b.) Set the table margin to 0 (see Figure below) in the HTML code. You can edit it using a text editor such as Notepad++.

c.) Be sure that in your iframe code, the width of your iframe is greater than the width of your applet. This is the same with the height. If scrollbar still appears, try to increase  iframe width or height.

Problem 3: The text Created with GeoGebra appears at the bottom of my applet.
Solution: Using Notepadd++ or any text editor, delete the text containing the Created with GeoGebra at the bottom of the  HTML code.

If you encounter other problems and found a solution, please feel free to comment below.

Note: Again, this is only for hosted WordPress blogs, and this method does not work in WordPress.com blogs as of yet.
