Published: Thu, 01/13/11

 
Hi ,
 
You are receing this email because you indicated when you signed up for Grant's Updates that you are taking Stat 1000 this term.  If in fact, you do not want to receive tips for Stat 1000, please reply to this email and let me know.
 
Throughout the term I will send you all sorts of tips to help you study and learn the course.  You probably already have done so, but, if not, I strongly recommend you purchase my Basic Stats 1 Study Book.  You will find it a great resource to learn the course.  I pride myself in explaining things in clear, everyday language.  I also provided numerous examples of all the key concepts with step-by-step solutions.  You can order my book at UMSU Digital Copy Centre at University Centre at UM campus.  They make the book to order so please allow at least one business day.  The book is split into two volumes and each volume costs $45 + tax.

Tips for Web Assign HW01
Study Lesson 1 in my study book (if you have it) to learn the concepts involved in HW01.  This lesson will also set you up for HW02.
 
Anytime a question wants you to "fill in the blanks" with key vocabulary terms, go to the appropriate section of your textbook (remember you have an online version of the textbook in Stats Portal if you selected the electronic option on your book list), and you will find the exact sentence they are giving you with the obvious word they want you to type in.
 
To type in the split stemplot they request, use the vertical line on your computer keyboard to separate the stem from the leaves ("SHIFT \" will give you " | ").  Don't worry if your columns don't end up perfectly lined up, just do the best you can.  Be sure to label the first line in your stemplot "Stem | Leaf", then enter all the stems and leaves row-by-row underneath.
 
Ignore any references to JMP 6SE or Crunchit!.  You are using JMP 8 in this course.  The assignment is just an old assignment that they forgot to update.  Use JMP 8 anytime they tell you to use computer stuff.
 
For the JMP 8 part of the assignment, here are some tips:
 
Once you have installed JMP 8 and opened it, you are shown a menu with various buttons to click.  You will almost always click "New Data Table" to enter new data.  In the rare event they have given you a JMP file with the data already entered in it, you will simply open that file which would probably already open JMP for you.  If you happen to enter data in yourself and save the file (a good idea), you can select "Open Data Table" to open up the saved file.
 
To copy and paste data into JMP: First, of course, select and copy the given data set.  Now, open JMP and click "New Data Table".  In the toolbar at top select "Edit" then "Paste with Column Names".  That pastes all the data in and names the column appropriately.
 
Double-click the column heading for each quantitative variable in your table and make sure the Data Type is Numeric and the Modeling Type is Continuous, using the drop-down menus to fix that if necessary.  Click OK.
 
To make a histogram: In the toolbar at the top, select Analyze then select Distribution.  Select the column you want the histogram for and click the Y, Columns button.  Click OK.  Your histogram appears sideways.  If they want to see it the typical way (and they will request that if they want it), click the red triangle next to your variable above the histogram and select Histogram Options from the drop-down menu.  Select Horizontal Layout.
 
For the pole-vault question: You will have to enter the data manually into JMP.  Click "New Data Table" to enter new data.
To enter data into JMP manually: Click "New Data Table" and you are automatically taken to an empty spreadsheet with one column.  If you ever need two or more columns, simply double-click the space to the right of "Column 1" to create "Column 2".  You can repeat this to create "Column 3", etc.  You can then type in the data, using "enter" or "tab" or your arrow buttons on your keyboard to move from one cell to the next.
 
In this particular pole-vault question, double-click "Column 1" and name it "Year".  Click OK.  Double-click the space to the right of Column 1 to create Column 2.  Name that column "Height".  Type in the data you have been given.
 
To make a Time Series: Select Analyze in the toolbar, then select Modeling in the drop-down list and finally select time series.  Select your time variable and click X, Time ID and select your variable you are tracking and click Y, Time Series.  Click OK.  Just ignore that other pop-up menu asking about time lags or autocorrelations or whatever, click OK and move on.  None of that has anything to do with the time series.
 
To get rid of any outputs you don't want to copy and paste, click the red triangle and deselect the unwanted things.
 
To copy and paste the parts you do want, select the icon on the JMP toolbar that looks like a fat white plus sign "+" (the Selection tool).  You can then click various parts of the printout to select the sections you want.  Copy and paste into Word or something like that.
 
Note, you must save your document as a PDF file to upload it into Web Assign (no other format will be accepted).  If you don't know how to do this for the software you are using try the help files or Google "save as pdf file" for some helpful steps or programs that enable you to save documents that way for free.  MS Word 2007 is capable of saving as pdf.  If you are using a different program and do not have a "save as pdf" option, Google "pdf995 download" for a free program that can be used to save documents in a pdf format.  Note that, if you are using a program like this, often it loads a "pdf printer" onto your computer.  Then, to save your file as pdf, you actually select "print" as though you were going to print your file, then select your "pdf printer" rather than your physical printer in the print options.  That will then save your file in pdf form.
