MAT200 Guideline Sheet for Paper 1 According to the MINITAB instruction sheet, there are ten printouts to generate which are on the instruction sheet. In your report answer the following questions: 1. 2. 3. Which variables are quantitative? Which variables are categorical? Where is the location of the median? From your professional histogram, what are the end points of the bins? Construct a frequency table bins frequency You may have to adjust your end points of each bin so you get the correct frequencies as your printout. 4. 5. From your professional histogram, does it look like the distribution is skewed to the left, the right or symmetric? Give justification by comparing the median with the mean What percentage of data is in each of the following intervals? x s, x s x 2s, x 2s x 3s, x 3s 6. 7. 8. 9. 10. From the stem-and-leaf display, on what stem is the median located? Do a side by side stem-and-leaf display. You may have to combine some values of a categorical variable so you have only 2 categories. How is the data distributed on each side? Compare the two stem-and-leafs. From boxplot give the 5 number summary. Calculate the Interquartile range (IQR) = Q3 Q1. Find the intervals where mild outliers could occur and where extreme outliers could occur. Give the data values which are mild outliers, and extreme outliers. For your side by side boxplot, which categorical value has the largest Interquartile range. Give the exact value for each Interquartile range.
