COMPUTER ASSIGNMENT EVALUATIONStatistics 135, Spring ’03Please answer the following questions thoughtfully and constructively. Your input will be con-sidered in the in future design decisions.Screen shots of each of the computer exercises appear interspersed throughout the evaluationform. They are there to help you remember the graphical user interfaces (GUIs), and to allow youto write comments on them.Thank you for taking the time to complete this survey.THIS EVALUATION MUST BE HANDED IN BY NOON ON WEDNESDAYMAY 21 IN ORDER TO RECEIVE CREDIT. YOU MAY EITHER HAND IT DI-RECTLY TO ME (PROFESSOR NOLAN) OR YOU MAY WRITE YOUR NAMEON IT AND PLACE IT UNDER MY OFFICE DOOR (395 EVANS).1The Sampler GUIWhat did you think was the main point of this computing exercise?What statistical lesson did you learn from the using the GUI?Please compare the computing exercise to the material presented in the book and lecture. Howwere they similar/different?What features of the sampler GUI did you find were easy to use?What did you find confusing or frustrating about the exercise?Please give ideas that you have for improving the interface.23The Experimental Design GUIWhat did you think was the main point of this computing exercise?What statistical lesson did you learn from the using the GUI?Please compare this computing exercise to the material presented in the book and lecture. Howwere they similar/different?What features of the GUI did you find were easy to use?What did you find confusing or frustrating about the exercise?Please give ideas that you have for improving the interface.45The simple regression GUIWhat did you think was the main point of this computing exercise?What statistical lesson did you learn from the using the GUI?Please compare this computing exercise to the material presented in the book and lecture. Howwere they similar/different?What features of the GUI did you find were easy to use?What did you find confusing or frustrating about the exercise?Please give ideas that you have for improving the interface.67The Radon MapIn this exercise, you were to compute county percentages via a spreadsheet and import theminto the colorMap GUI. You also were to compute a state estimate and confidence interval.Did you find that using the spreadsheet reinforced the statistical concepts behind stratifiedsampling or not? Please explain.Did you find the spreadsheet computations easy to make?What did you find confusing or frustrating about the spreadsheet calculations?What features of the colorMap GUI did you find were easy to use?What did you find confusing or frustrating about the colorMap GUI?Please give ideas that you have for improving the interface.89The DNA pattern GUIIn this exercise, you were to compute chi-square tests for the uniform and Poisson distributionsvia a spreadsheet. You also were to analyze the locations and gaps of the palindromes via specialgraphics such as the sliding bin plot and exponential quantile plots.Did you find that using the spreadsheet reinforced the statistical concepts behind goodness-of-fittests o r not? Please explain.Did you find the spreadsheet computations easy to make?What did you find confusing or frustrating about the spreadsheet calculations?What features of the graphing GUI did you find were easy to use?What did you find confusing or frustrating about the graphing GUI?Please give ideas that you have for improving the interface.1011The Data Analysis GUIThe data analysis GUI evolved over the course of the semester. It was used three times : toanalyze birth weights of babies born to smokers and nonsmokers; to analyze premolt and postmoltsize of crab s hells; to analyze the snow gauge data.Some features were added to the GUI and others were changed as the semester progressed.1. For the birth weights, an instruction sheet app e ared in the top right panel of the GUI. Theinstruction sheet did not appear the next two times the GUI was used. Did you find it was helpfulto have it, or it did it not matter if it was there or not? What improvements to the sheet mighthave made it more useful?2. In the first lab, the transcript of numerical output appeared on top of the plots, and inthe next two labs, it appeared next to the plots. Do you have a preference for where it should belocated? Why?3. The DNA lab provided a table that you could fill with up to 4 plots. Would you prefer thisinterface to this one where you have one plot per page but an unlimited number of plots that canbe made?4. Please comment on the interface for choosing variables to be analyzed.125. Please comment on the annotate plot feature where you can place a curve on a scatter plot.What other types of annotations would you like to have available?6. Please comment on any other features of the GUI. What did you find useful, easy-to-use,confusing, not useful. What additional features would you like to have?131415Please provide any overall comments that you have on:1) The use of case studies to teach mathematical statistics.2) The use of computing in the mathematical statistics course to address statistical conceptssuch as the ce ntral limit theorem.3) The use of the computer in the mathematical statistics course to apply the statistical conceptsand analyze data.4) Other Comments:16About you:Male FemaleYears at Berkeley Standing (i.e. junior, senior, graduate)Grade you expect in STAT 135MajorDescribe your experience with the following software and operating sys tems .
