Group tutorials on friday

Today we had one of our friday tutorials with Darren. Each one of us brought a bunch of research material and shared it with a group. It is very fascinating to have so much information in an hour. There were a lot of interesting examples of graphic communication for each variables that we have.
Here I want t share my research outcome of last week. I made a slideshow and printable version. Why did I choose a slide show? Because it's easier for me to receive an information when it's in the way of movie and sound. Moreover it is fun and I think that when you are doing your research you have to enjoy it and avoid all the thing that could somehow get you bored. However I made PDF as well in case if for someone it's a best format to get the information.
