Assignment # 3 – CROSSTABULATIONS and CHI-SQUARE

Using the 2004gss_revised.savdata file (found in “2004 GSS Files” folder), conduct bivariate analyses to determine which hypothesis is more accurate. Remember to request column percentages.

1.State the independent and dependent variables. Only the variable name would suffice.

a.Independent variable: ______

b.Dependent variable: ______

If you want to find out more about these variables and what the literal question in the Survey was, please go here>. (Hold _Ctrl_key and click the link)

2.What percentage of those who oppose capital punishment report supporting abortion?

______

3.What percentage of those who are in favor of capital punishment report supporting abortion?

______

4.Which hypothesis is more accurate?

______

a.Why?

______

5.Create two (2) additional crosstabulations with CAPPUN as the independent (column) variable and ABDEFECT and ABSINGLE as the dependent (row) variables. Paste those 2 tables here:

______

6.What is the epsilon value of supporting abortion in the case of a birth defect between those who favor and those who oppose capital punishment?

______

7.What is the epsilon value of supporting abortion in the case where the mother is single between those who favor and those who oppose capital punishment?

______

a.Is this bigger or smaller than the above epsilon (for birth defect)?

______

b.What does this mean?

______

CHI-SQUARE(50 points)

Same file: 2004gss_revised.sav

As we know, association means that two variables are related to the extent that knowing a person’s attribute on one will help you guess his or her attribute on the other. With this in mind, hypothesize that one’s views on capital punishment effect how they feel about believe in life after death.

1.State the Null and theAlternative Hypotheses:

  1. Null Hypothesis (Ho):______
  2. Alternative Hypothesis (Ha):______

2. State the Independent and Dependent variables. Only the variable name would suffice.

  1. Independent variable: ______
  2. Dependent variable: ______

3.Run the crosstabulation. Paste only the appropriate tables here (i.e.: Lambda and Chi-Square tables):

  • Lambda table goes here…

______

  • Chi-square table goes here…

______

4.What is the value of Lambda? What does it mean?

______

5.What is the value of Chi-Squaretest? (Remember: you report in the p-value).

______

6.Based on the Chi-Square value, do we reject or fail to reject the Null Hypothesis at the .05 significance level? Report in APA style and then elaborate shortly in plain English, as if you were presenting it to a non-statistician person. Did the test reveal that those who believe in life after death are more supportive of death penalty?
