Displays are attached according to the appearance of question. Example: question 2 is discussed first, so the first display belongs with question 2 and so on.

2. The questions we chose for our displays were questions 2, 3, 6, and 7. Questions 2 and 6 are numerical and questions 3 and 7 are categorical.

For question 2, we chose to do a dot plot in Tinkerplots for how many credit hours students are taking. We knew that this was appropriate because question 2 is a numerical question, and a dot plot is a numerical display. Another reason we felt this was an appropriate way to display our data because there is a small range of numbers so our scale would not be too big. Also, the highest number of students with the same number of credit hours is 40, which was not too high of a range either. Along the bottom, there is a consistent scale of 1 that complements our data. Although there is a large …show more content…
We knew this was appropriate because question 7 is categorical, and stacked bar graphs are a categorical display. Another reason this is appropriate is because it shows the part to whole relationship comparing each category to the whole. Since there are only three categories, it is easy to tell how much of an influence each category has, and that is shown by the percentages.

3. For question 2, we used mean to find the measure of center, and the mean is 14.25. We chose the mean because there is not a very high range of numbers, and there are no outliers. Since the mean is not resistant to change, outliers greatly affect the mean, so using the mean with outliers is not representative of the measure of center. Since 14.25 is the mean,the amount in each of the eight groups was evenly distributed in order to find the mean. That left each group with 14.25, so that means a full time WMU student who has declared their major takes about 14 credits per semester on
