## Which measures are appropriate for nominal, ordinal, or interval/ratio variables? What do these measures tell us about each variable?

Assignment 1: Research Guidelines

Complete the following assignment by filling in all pertinent areas of research.  You will need to utilize SPSS and the GSS dataset for this assignment. You should complete this assignment using the variables and topic that you have chosen for your Final Portfolio Project.  You will then be able to follow this as a guide as well as a check-point with your instructor.  It is essential that you read through all of the feedback regardless of your score.  You will be required to submit:

1. This word document with blanks filled and SPSS outputs inserted.  Throughout the assignment you will see places where your tables, charts, and graphs can be placed.
2. An SPSS output file (spv) with this assignment for credit.

You may need to go back through the document to address formatting issues that may shift as you begin to input your data.  Points will be deducted for sloppiness.  Please treat this as a professional outline used for a proposal.  Use a different, but legible, color font for your responses.

This assignment is to completed and submitted no later than the Sunday of week 3 by 11:55pm ET.  This assignment is worth 60 points.  Save the word file as follows [your last name_SOCI332_A1] and submit it to the dropbox for feedback. Label the SPV file as [your last name_SOCI332_A1output]

• Frequency Tables ( /10 pts)

Run frequencies for each variable listed above.  Summarize your findings in a paragraph or two below.  What do the counts and valid percents tell you about each variable? Cite numbers in the frequency tables to support your conclusion. Be sure to insert your tables (copy and paste from SPSS) into this document.

• Graphs and Charts ( /6 pts)

Run the appropriate graphs/charts for each of your variables listed above.  Summarize your findings briefly in a paragraph or two.  Cite numbers in the graph/charts to support your conclusion. How does the visual representation help us understand the data? Include a title on each of your charts and other pertinent labels.

• Measures of Central Tendency and Dispersion ( /10 pts)

Run the measures of central tendency (mean, median, mode) and dispersion (variance, standard deviation) for each of your variables. Summarize your findings briefly in a paragraph or two. Which measures are appropriate for nominal, ordinal, or interval/ratio variables? What do these measures tell us about each variable?

• Recoding ( /10 pts)

Choose one of your variables to recode. If you have an interval/ratio variable, you may recode it into an ordinal variable. If you have two nominal/ordinal variables, recode the one with the most categories into fewer categories, or check with your instructor on the best option.

[Insert the following items: SPSS syntax for the recoding process; the frequency table for the original variable; and the frequency table for the recoded variable]
