Here are the definitions of the graphs that I will be using for my interpretation of the data: A histogram is “often used in exploratory data analysis to illustrate the major features of the distribution of the data in a convenient form. It divides up the range of possible values in a data set into classes or groups.” It is almost like a bar graph, but instead of categorical data, a histogram displays the frequency of numerical data. The graph on the left is an example of a histogram that I made in my Statistics class earlier this year for a Pi Day Project. We had to determine if the digits of pi could be used as a random number generator. We came to the conclusion that it can indeed be used because the probability of each number occurring is very close to .1 or 10%. For more information about this, you can visit my teacher, Mrs. Blanchet's blog. A box-plot, also known as a box and whisker plot, is a “type of graph which is used to show the shape of the distribution, its central value, and variability. The picture produced consists of the most extreme values in the data set (maximum and minimum values), the lower and upper quartiles, and the median. An ogive is similar to a histogram, but instead of displaying individual frequencies, it displays the cumulative frequencies. And a stem plot is “similar to a histogram but is usually a more informative display for relatively small data sets… It provides a table as well as a picture of the data and from it we can readily write down the data in order of magnitude, which is useful for many statistical procedures… By using a back-to-back stem plot, we are able to compare the same characteristic in two different groups.” I got all of these definitions (except for ogive) from this website.
means. Also within this link, there are many other statistical terms that you may not know the definition of. This link was very useful for me because it explains the term in depth and for the terms that I knew but forgot, this was a review. Back to gathering the data; well, I was able to get in touch with two of the schools via phone, but one school I had to email. I told each of the schools to give me back to data by mail by Friday (tomorrow). This means that they if they postmark the one-question survey that I have asked them to give to the students by tomorrow, I should have my data by Monday. I asked them to send it to my school because it will be easier for me to get my data rather than it being delivered to my house and then me having to bring it to school. I am really glad to know that my project is on its way and it is finally getting somewhere. I am planning on calling other schools that I was not able to get in touch with tomorrow during class. One of the reasons that some schools did not answer was because they were conducting standardized testing and could not be disturbed. Hopefully when I call them during my Statistics class, they will be able to talk with me and I can tell them all about my wonderful project! :)
I just went to read the blogs of other students in my AP Stats class. [I have attached links to the blogs of other students on the right of this blog.] They are really good! Each experiment is unique and it will take a lot to do these projects and get all the information, especially with all the things that are required of us. This project is a really good idea because we actually get to explore the community in math class -- now that's something that I though I would never do! I am really looking forward to gathering my data and also seeing what kinds of data other people are gathering. I guess I finally understand what people mean when they say that the world is just waiting for people for explore all the opportunities.
Check this link out to a blog that a parent wrote about the hours of homework students spend each night. And basically, he does not want students to have so much homework each night. I FULLY agree with this!!!!!!!! In his blog entry, he states that doctors base their treatment of their patient based on the patient's condition, and not based on their knowledge of science and medicine. Of course having a science and medicine background allows their judgment to be better, it is not as effective as the gut feeling a person may have. Christopher, the author of this blog entry, also gives a schedule of an average teenager. He states that 12 hours are spent to maintain a good health. This is half of our day. Then, about nine hours is spent on structured activities, such as, time spent at school, time spent commuting, and then the time spent on extracurricular activities. Now, the total is twenty-one hours. This only leaves three hours for the person themself. And you can’t forget that the human race is not perfect and there can be some distractions, which can extend this time. The student still needs to be relaxed in those three hours, have time for maintaining their hygiene and some other personal things. If teachers were to assign three hours of homework each night, the student would not have time to do anything else and would be grounded in work. This is not healthy for the child and teachers should keep in consideration the schedule of students outside of schools and assign an adequate amount of homework.
