IBM Deliverables
1. Do survey participants who have different IT roles (Q1) differ in terms of dimensions of overall measures (Q4-Q7) when these variables are considered simultaneously? Since there are no value labels in the IBM data set, assume role 3 to be IT.
2. Do survey participants who have different IT roles (Q1) differ in terms of dimensions of image (variables Q8-Q17) when these variables are considered simultaneously?
3. Do survey participants who have different IT roles (Q1) differ in terms of dimensions of purchase (variables Q18-Q21) when these variables are considered simultaneously?
4. Do survey participants who have different IT roles (Q1) differ in terms of sales and service support (variables Q22-Q26) when these variables are considered simultaneously?
5. Do survey participants who have different IT roles (Q1) differ in terms of future trends variables (Q27A-Q27G) when these variables are considered simultaneously?
6. Can the image variables (Q8-Q17) be represented by a reduced set of variables?
7. Can the likelihood of purchase variables (Q18-Q21) be represented by a reduced set of variables?
8. Can the sales and service support variables (Q22-Q26) of the questionnaire be represented by a reduced set of variables?
9. Can the future trends variables (Q27A-Q27G) of the questionnaire be represented by a reduced set of variables?
Do not forget to review the synopsis of each data set. You will need to upload each SPPS output separately.
Including a Narrative in Your SPS Output File
You will note that some of the questions require you to interpret the results. SPSS allows you to include a narrative at any point in the Output file. To include a narrative, follow these simple steps:
Go to the point in the Output file that you wish to insert new text (highlight the point on the menu to the left), and then go to Insert => New Text.
Including any text in the Output file will reduce the amount of work you need to do in creating a Word document for the narrative. Consequently, you will only have to submit one file (the SPSS Output file) rather than multiple files.
SPSS Steps:
- Multiple Regression:Go to Analyze =>Regression =>Linear=>Select Dependent Variable (scale data only)=>Select Independent Variables (usually scale data but can contain nominal)=>OK.
- Discriminant Analysis:Go to Analyze => Classify => Discriminant => Grouping Variable (must be nominal data) => Define range => Independent Variables (scale data) => Statistics => Box's M => Classify => Summary Table => OK.
- Factor Analysis:Analyze => Dimension Reduction => Factor => Select Variables (must be scale data only) => Extraction => Scree Plot => Continue => OK.
Important: Do not restrict yourself to the steps listed. Have fun and experiment with options/layout/different stats options/graphs, etc. Read up on how to interpret results.
