Assignment A3

Due: January 22.

Univariate Statistics

In this assignment you will be using the GSS data set.

Go to the NORC web site http://gss.norc.org/get-the-data/spss and choose the year 2016 under Download Individual Year Data Sets (cross-section only).

Download the zipped data file.

Unzip the file to get GSS2016.sav.

Take your chosen dependent variables from GSS and two likely independent variables.

Run frequencies and descriptive statistics (minimum, maximum, mean and standard deviation).

Create bar chart for all three variables.

Then recode them into dichotomies.

Run frequencies on these new variables and check for mistakes.

Create a pie chart for each.

Get the frequencies for the main dichotomous dependent variable for each value of the first dichotomous independent variable then the second one.

Write a few paragraph (not more than a page) explaining the meaning of your output. Hand in your explanation and output file via TED  (TritonEd) in a single file. You can use Copy and Paste to move the output from the SPSS output file to the Word file.

To create the dichotomies:

Transform -> Recode into Different Variable [Name Output Variable] -> Old and New Values
Then you specify the Old Value then the New Value  then -> Add
So if the 1st and 2nd groups (Old Value = 1,2 or Range 1 thru 2) should be collapsed into one (the 1st group or New Value=1) you will see in the right lower window 1 thru 2  --> 1. Etc.
-> Continue 

To get the frequencies :

Analyze -> Descriptive Statistics -> Frequencies
Then you choose the variable(s) from the list in the left window and move it to the right window.

To get the descriptive statistics:

Descriptive Statistics -> Descriptives

Then you choose the variable(s) from the list in the left window and move it to the right window.

To get the bar and the pie chart:

Graph -> Chart Builder

From the Gallery below choose Bar and choose the proper version (in this case the first one in the top row)

In the window above you will see some bars and a rectangle below them with the text X-axis?

Pull over from the variable list the variable that you want to use and put it into that rectangle.

Click on ->OK.

To get the frequencies of the dichotomous dependent variable for each value of the first and second dichotomous independent variable you will use Split File:

Data -> Split File

Choose Compare Groups and drag over the first dichotomous independent variable from the list on the left to the window (Group Based on) on the right.

Click OK.

Then do the frequencies.

Replace the first dichotomous independent variable with the second one. Repeat.
