# Conduct a Contrast analysis on Gender, the factor variable.

**Excel and SPSS e-Portfolio Guidelines**

The Excel and SPSS Portfolio will consist of all the Microsoft Excel and SPSS

lab assignments.

It should be in the same sequence as that of being instructed, generally from lab assignment 1 to 8.

The portfolio will consist of a cover page for the entire portfolio and will also consist of a cover page for each lab assignment. The format of the cover page for the entire portfolio and each lab assignment is provided below.

The written text will be double-spaced, font size 12, and Times New Roman.

Please set the Top, Bottom, Left, and Right Margins to 1 inch.

Each lab assignment should have its own cover page, followed by the explanatory paragraph, and printed output pages.

**The Excel and SPSS Portfolio must look professional**.

The Portfolio must consist of a cover page followed by table of contents, followed by all computer laboratory assignments.

Sample portfolio are available with peer tutor and instructors, please feel free to stop by and look at the old sample portfolios.

**PLEASE NOTE THAT THE PORTFOLIO IS SUBMITTED DIGITALLY AS A SINGLE PDF FILE TO DROP BOX ON D2L**

**Please note that the explanatory paragraphs, the title page, table of contents, and title page for portfolio will all be written in word document and converted to PDF.**

**The lab outputs for excel, where you will create the tables will be copied and pasted into word document and converted to PDF document. The output**

**from SPSS will be exported to PDF.**

**Now when time comes to make everything into one file then you can use one of the several available online PDF joiner websites to join your various PDF files in correct sequence and order of the e- portfolio and make them into one single file.**

**For the table of contents, the page numbers are optional, you can insert the page numbers if you have Acrobat Professional (optional).**

**Please make sure you submit it by the due date and time, only one single file can be uploaded to D2L.**

**Failure to comply with these instructions will result in a failing grade**.
