Bean+Measurement


 * Bean Measurement**

__Introduction__ This activity was about classifying and measuring the beans. I and my partner were given a cup of various kinds of beans. We classified those into several groups and measured the average size and mass of each bean. And then, we used that data to observe whether there is a correlation between average length and average mass of the bean.

__Evaluation__
 * 1) Things that went well :** One thing that went well in this activity was that the cooperation we had. While I was lining up the beans and measured the length, she was measuring the mass of the beans that I measured previously. Like that, we went through the experiment pretty fast.
 * 2) Things that didn't go well :** But, one thing that I felt hard was when we were classifying the beans into groups. There were some beans that looked somewhat similar and somewhat different. In other words, it was hard to tell differences between some kinds of beans.
 * 3) What I learned :** However, I learned that there "seems" to be no particular relationship between average length and average mass of the bean.
 * 4) What I will change next time :** Next time, when another chance to redo this process comes, I would measure more various beans and actually calculate the regression line that may fit to the data and check its accuracy.
