This research is about an experiment we did in the writing composition class, this semester at the University of Texas, San Antonio. We worked as a group of four on the experiment. For our first task we were given a container of black and white beans mixed and our task was to find out the number of black and white beans, the percentage of each kind of beans, and make a graph accordingly to represent our findings. The second task was to take a random sample of both kinds of beans and compare the results to our finding of the first task. The random sample was to be taken twelve times.
Research question 1: Is the percent of black and white beans the same as the first sample experiment?
Research question 2: What happens if we repeat this random sample twelve times (replacing the beans each time)?
For our second task we took a handful of black and white beans and mixed them up in a container. We did this twelve times and each time counted both the beans separately. The table below depicts the result of all the twelve times.
Our prediction was that black beans will be 72 and white beans will be 30. However, when we counted we found out that black beans were 80 and white beans 40.
In all the findings we noticed that the black beans were more in number than the white ones. The reason for this was that we were given black beans more in number than the white ones. In our next study we will compare the findings and results of the other groups in our class for a cumulative research and result. We will make a similar table like the one above, for each group and compare the results. We will find out whether other groups also had black beans more in number than the white ones or not. After comparing we will take an average of the black and white beans to see how many white and black beans we all were given as a class. To go further into our research we could also find out which group had the most number of beans altogether, or if we all were given the same number of beans altogether but different numbers of black and white beans.
