Statdisk Assignments
STATDISK Laboratory Manual to accompany STATDISK version 9.5.x, Triola
2. Required STATDISK assignments are listed below. Corrections and suggestions for completing the problems are included. It is very important to read the instructions at the beginning of each STATDISK manual chapter in order to understand how to use the program's modules for that particular chapter. If you are using the videos, there are directions about each module on the STATDISK video (#00) provided in the video set.
3. STATDISK assignments are due on the day of the exam deadlines. See the Course Calendar for these required dates. Bring to my office GN 123. If you are taking your exam at a time when my office is closed (example, Saturday), a box will be available in the Testing Center to leave your STATDISK folder in.
4. To turn in the STATDISK assignments, please tear out the appropriate pages (only those that have required problems on them). Staple these pages together (no loose pages, please), make sure your name is on the first page, and place in the right hand pocket of the paper folder - no hardback notebooks please. The POINT SHEET should be placed in the left hand pocket of the folder. Make sure your name is on the POINT SHEET.
On the front of the folder in the upper right corner, put the following:
Your Name
MATH 1530 Section VT1
STATDISK Folder
If you have a dark colored folder, please use a white sticker to write the above information on.
5. STATDISK pages that have been graded and returned to you are to be returned to the instructor the next time you turn your STATDISK folder in (after you have reviewed the grade you received on these pages). These pages should be put behind the POINT SHEET in the left pocket.
6. Circle each required problem number.
7. Some STATDISK exercises require printouts of histograms, boxplots, etc. The printout should be identified as "yours" by printing your name at the top of the document using STATDISK. The new version of STATDISK allows you to do this. You should also indicate which problem the printout is associated with using the problem number. Also the problem number should be indicated on the printout. The new version of STATDISK will allow you to do this.
IMPORTANT: The printout must be placed directly behind the page of the exercise when turning in STATDISK pages for grading purposes. Do NOT put the printouts at the end of all the pages being turned in.
8. Each problem is worth 3 points, except where noted.
Chapter 2: 1, 2, 3, 4, 5, 9, 10, 12, 17, 18 (20pts) Total Points: 47
#9: In Dataset drop down menu, use CHMOVIE file
#12: Put both data sets on one graph - plotted as (x,y) values in a Scatter Plot
#17: Be sure to choose data that is ratio in nature (see Chapter 1). A copy of all the collected data must be provided. Keep a copy of problem #18 as you may want to use this same data for your Writing Project.
Any time you are asked to indicate a probability
which has been simulated from STATDISK, you should give the fraction first,
then the decimal value.
(Ex: 12/80 = 0.15)
#5 through #8: As with any simulation, a large number of trials should be run. The number of trials you decide on will be your denominator. Count the number of trials that have the characterisitic desired (ex: #5 how many trials had at least 6 correct answers); this will be the numerator of your estimated probability. Be sure to change to write both the fraction and the decimal form.
#1 and #2: Provide worksheet of computations
#3: Print the histograms of the various dice experiments.
** #1 and 2 can be started after completion of study of text sections
5.3
** #3, 4, and 5 can be started after completed of section 5.5
3. For problems where you need to determine the number of successes (x),the proportion, or mean and standard deviation, write those values in the margin.
4. For each problem, underline the few words that identifies the typeof claim (=, <, >, etc) the problem is about. For example, #1, you would underline the words, "...proportion of adult Minnesotans opposed to photo-cop legislation is greater than 50%." In #2, you would underline, "... is less than 10% of all adults....."
BE SURE you change the claim field in the Hypothesis Testing module to the correct symbol (=, <, >, etc) for the claim of the problem!! Click on the arrow next to the field to find the other options.
#1 - 4: print scatterplots
#3: Use BEARS dataset; weight is in column 9; age is in column 1
**can be started after completion of study of the regression equation (9.3)
2. Underline the part of the problem that identifies what type of problem it is. For example, #1: "test the claim that the outcomes are not equally likely."; 10-10: "..test the claim that response is independent.......".
3. Several problems do not state an alpha level; use 0.05.
4. Correction #9: Use handout sent in email (or handed out in class)
5. #12: provide the contigency table that must developed
STATDISK Total Points 300
All STATDISK pages must be returned by the end of the semester.
