Posting Videos on Class Wikispace

You first need to create a video and save it as a file or obtain a URL. You can use any software to create your video. I used Jing for this demonstration. Let's watch the video from http://statistics401dxw-isu-spring2011.wikispaces.com/.

Extension for Gapminder Story Assignment

The new due date is April 2nd, 2011.

How to Capture Images or Create Video for your Gapminder Story?

Hello everyone,

I have been using the PrintScreen function on the keyboard to take a picture of my Gapminder graph.

However, today, a friend told me about a new software called Jing that can take a picture or make a short video of what you see on your computer screen. It can also let you share your video and picture instantly on the web.

This will be a nice way to capture an image and/or create a video for your Gapminder story. I encourage you to check it out. It is very simple and easy to use. You can download the software, watch the tutorial, and try it with your own story.

First you can learn to capture a still image using the Capture Image option, save, copy and paste it into your document.

Then try the Capture Video option to create a video to show the animation of your story. You can then obtain a link to the video and share it on the our wikispace or via email, web, etc. Here is the link:

I will demonstrate how to use Jing in Lab on Thursday. Check it out before Lab if possible.
If you know any other methods of screen capture, please share.

SAS code for Fisher z-transformation

If you are interested in using SAS for question c in Lab 7, you can use the code below:

TITLE Fisher z-transformation correlation test;
PROC CORR data=crime Fisher(rho0=.5 alpha=.01);
VAR violent poverty;
RUN;

I recommend doing this question by hand to find the test statistic z. SAS does not provide this value z. However, you can use the p-value in the output to decide whether or not to reject H0.

The Use of Simple Linear Regression

http://www.gapminder.org/videos/200-years-that-changed-the-world/


This is a "must-watch" video as it is closely related to what we discussed this week. I'm developing it into another extra-credit activity and will elaborate that in Lab next Thursday 3-10-2011.

Please post your comments here. Here are some suggestions:

• Discuss the relationship between Life Expectancy and Income per person.
• Discuss the use of graphics as tools to visualize Data. Specifically, look at the graph,
  

Explain the axes:
What is the vertical axis?
What is the horizontal axis?
Then explain the bubbles:
What does each bubble represent?
What does the size of the bubbles represent?
What does colour represent?

• How do you think the Life Expectancy variable was measured for each country?
• What is another term used to describe the Income per person in a country?
  
• How was the situation in 1800?
  
• Ect.

Above of all, enjoy the video and share your thoughts.

"The Joy of Statistics" Video

http://www.gapminder.org/videos/the-joy-of-stats/

I hope you enjoy watching this informative video. More than ever, I'm proud to be a statistician and an educator who spreads the word of this wonderful science called Statistics. This movie helps to dispel the myth and the "accusation" some people have on statistics: "There are three kinds of lies, Lies, damned lies, and statistics".
What do you think?

Please share your thoughts and comments after watching the video.
