Statistics: Making sense of Data : Box plot

From today, I start to study statistics through coursera.org. I am pretty sure many people already know about the website. The website offers a variety of university programs to public for free. You can choose any subject which you are interested in or you are already studying in your class. It is very useful and helpul for people who want to gain college level courses from prominent universities throughout the world.

My first choice among these courses is 'Statistics: Making sense of Data'

To resume my story, the first device I learned today was 'Boxplot'. I was used to the chart because I often saw the type of graph when I was at work. But I had no idea of what the chart was. Finally I got its meaning of figure. Box plot represents 5 certain points out of a data set, which are

1. maximum

2. the third quartile (75%)

3. median

4. the first quartile (25%)

5. minimum
