When completed, this assignment should be between 3 and 6 pages long (1 - 2 pages for charts/tables, 2 - 4 pages for analysis of given data) and there is a grading rubric below. Grading Rubric Charts/Tables/Values (5 points) -1/2 for errors with mean, median and standard deviation -1 for missing/incorrect charts/graphs Analysis from given data (5 points) -1/2 for incomplete pieces (lacking in intro or summary, not fully thinking about different perspectives, not containing any speculation) -1 for missing pieces Discussion of limitations and extensions (2 points) -1/2 for incomplete pieces -1 for missing pieces Test scores for all of the students in class X 77, 81, 72, 76, 68, 75, 69, 80, 78, 72, 73, 67, 82, 79, 70, 74, 82, 68, 71 Test scores for all of the students in class Y 83, 55, 61, 89, 91, 95, 74, 79, 49, 86, 48, 68, 72, 75, 80, 86, 99, 92, 71, 55, 52, 70, 92, 83, 62, 71All writing assignments need to be typed, double-spaced with standard margins and font. Examining test grades from two different classes. Statistics is the science of collecting, organizing and summarizing data in order to make conclusions and predictions. For this assignment you will be given data and focus what can be done after you have that data. So this assignment will focus on the organization and summarization of data and will finish with a brief consideration of limitations and extensions. You are given exam scores for the students in two different classes (class X and class Y). Before you start writing, you need to collate the data. Still treat these as sample data because these are not all the students in the school. You will organize the data by making a comparative stem and leaf display. You will then break the grades down into letter grades A, B, C, D and F (we will not use any + or - grades) and will make a comparative bar graph of the two classes based on those letter grades. You get to decide what numerical grades are A, B, etc but make sure you include this in your writeup. Finally you will find the mean, median and standard deviation for each class. Once you have your graphs and values you are ready to start writing the paper. You will begin the writing assignment portion by introducing statistics in general and describing how charts/tables and other statistical values are used to summarize data and address the particulars of this assignment (be sure to include a thesis statement). Follow this up by explaining/summarizing what you can from each data set and then compare the two data sets. Be sure to include some speculation on the circumstances that could have led to these results. Realize this isn't intended for you to explain how you made the graphs/charts or how you computed the mean, standard deviation, etc but is intended to explain what the graphs/charts and values are telling us. You will finish this assignment with a discussion of the limitations of the current data and how this could be extended to have a deeper discussion. You will probably need at least 1 paragraph to discuss each data set followed by a paragraph where you compare the two data sets. In this explanation you should make some guesses to explain why the data is what it is (some conclusions/ predictions) but be clear what is given by the data vs what is speculation. You should think of yourself as a student and discuss which class you might prefer to be in. You should also think of yourself as the instructor and discuss how you might interpret the results and the overall class performance. You'll probably need at least
