Statistics

For this assignment you will use some very basic procedures for file management.

Usually, a different procedure is used to download data files from what is used to view documents. For example, if you open a PDF file, your computer will probably notify you that the file being accessed is an Adobe PDF file, and you may simply choose to open that file in the Adobe Reader and read it on the screen.

You must use a different procedure when downloading data files in this course. For example, when you click the “jfile.dat” link in the Resources as part of the instructions that follow, you will likely be given the option to either open or save the file. With data files, you should always save the data file to the correct subdirectory (for this class, psy7615) on your machine and later use some application to open it. As you progress through the course, you will be asked to create a new subdirectory for each unit. Be sure you do not leave this unit without learning how to control the download process on your machine and learning how to download data files to a location where you can later find and retrieve them. For more information, review the study, Working With Data Files, earlier in this unit.

Process

Complete the following:

  1. Create a parent directory and subdirectories (also called “folders”) in the root directory of your chosen computer storage device (The c: drive or the flash drive).
  2. Download files from the courseroom and save them in the directories you have created.
  3. Rename the files you have saved in your directories as follows:
    • Using Windows Explorer (Windows Explorer is the program that opens when you use “My Computer” or “Computer” under the Start menu), select a location on your disk drive where you want to store your files for this course. It is mandatory that you create your course directory in the root of your c: drive, or the root of a flash drive.
      • Create a directory named psy7615 in the root directory.
      • Within the psy7615 directory, create two subdirectories named first and second.

      Note:If it is absolutely necessary for you to use another location (such as a Documents folder), you must contact your instructor. If you do not know what a root directory is or how to get to it , study the provided materials or contact your instructor.

    • Download the file jfile.dat, found in the Resources, and place it into the subdirectory you named first. Rename the file asunit1_data_names.dat
    • Download the file kfile.dat found in the Resources, and place it into the subdirectory you named second. Rename the fileunit1_data_nonames.dat
    • Create an ASCII text listing of your psy7615 directory and all subdirectories within it. See the help file in the Resources for specific instructions on this process. Name the directory listing file as dirlist.txt.
  4. Write a response on the role of statistics, using the steps that follow. If you need additional help, see the Unit 1 Assignment Help in the Resources.
    • Open the dirlist.txtfile with Microsoft WordPad (found under Start > All Programs > Accessories): First, open WordPad. Pull down the File menu (or the smaller box at the far upper left which has a downward arrow on it) in WordPad and navigate to your psy7615directory. If you cannot see the dirlist.txtfile when you know you are in the psy7615 directory, type *.* into the File Name slot, and click Open. The file should then appear, and you may have learned a new skill in opening files!
    • Carefully study the document in the Resources entitled The Role of Statistics in Psychology.
    • In the dirlist.txt file, just below your directory listings, write a 100–150 word response to The Role of Statistics in Psychology. Explain your goals in this course and in statistics training overall. Describe what statistics courses you plan to take in the future and what statistics courses you have taken previously, and discuss your experience in those courses. Be sure to include a reflection on statistics and as it relates to empirical research and critical thinking.
    • Save the dirlist.txt file as an RTF file in the psy7615 directory. To save the file as RTF, pull down the File menu (or the little box at the far upper left with the downward pointing arrow), and select Save As, then select Rich Text Format (*.RTF) from the Save As Type menu bar at the bottom of the Save Asdialog. Note that the new file will be named dirlist.rtf.
    • Attach the “dirlist.rtf” file to this assignment and submit it. The contents of this file will show that you have downloaded and renamed your files as requested in the assignment, and that you have created your course directory hierarchy properl
