Guidelines:

You may place your answers directly into this document. Use TAB to advance through the table below.

If the assignment asks you to perform a task, you should explain the steps for completing this task in enough detail so that someone else could do the task. For example: Let’s say the instructions are to “Make a Copy of Column1”. You might type “Click COPY button, select Column 1, click COPY button on dialog. Click on Column 2. Press CTRL-V”

If the assignment asks a direct question, you should answer the question in a full sentence. For example if the assignment asks “What type of data is this? Why?”, you might answer “This data is categorical data because it could be used to divide the data into 3 categories: SMALL

MEDIUM LARGE.”

Your answers should be typed in red.

Instructions Answers & Explanations

Open the STATDISK program, then open the data file ALUMINUM CANS using Datasets and then Elementary Stats, 13th Edition. This file contains the axial load measured in pounds of aluminum cans. Axial loads are applied when the tops are pressed in place. [Hint: Use the Datasets menu, as instructed in the STATDISK User’s Manual.] How many observations are there in the file?

Make a copy of the data values listed in column 1. Paste the data values into column 3. Re-name the title of column 3 to COPY. Explain the steps.

Make a copy of the data values listed in column 2 and paste those into column 4. Then sort only the data values in column 4 using the Sort Z to A. Label the column SORT. What is the largest value in this dataset?

Manually enter the following data values into column 5. Type all of the data values into the one column in a vertical fashion like the other data values are listed in the other columns. The order in which you enter the data values into column 5 does not matter. Label this new column FICO. Explain the steps.

698 836 768 532 657 559 741 792 701 753

745 681 598 693 743 444 502 739 755 835

What are some of the problems that could occur when entering data values?

Go to the Data menu, select Sample Transformations to add50 to all the data values in column 5 and then paste those values into column 6. Label column 6, FICO + 50. Now what is the value of the data item in the 10th row?

Would you consider the Cans 109 variable to be discrete, continuous or neither? Why?

What is the level of measurement for the Cans 109 variable? Why?

Save all of the data in columns 1-6 using the file name W1PROJECT. Be certain to add column labels to the data set. Explain the steps.
