·         Research Hypothesis: Those who oppose capital punishment also oppose abortion for any reason.

·         Alternative Hypothesis: Those who oppose capital punishment are in favor of abortion for any reason

Using the 2004gss_revised.sav data file (found in “2004 GSS Files” folder), do 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: ___ capital punishment _____

b.      Dependent variable:   _ abortion ______

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?

_79/321 = 24.61%_______

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

_171/321 = 53.27%_______

4.      Which hypothesis is more accurate? Why?

_ Capital punishment and abortion are independent of each other. Two variables are independent _______

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:

__

 Count FAVOR OR OPPOSE DEATH PENALTY FOR MURDER Total FAVOR OPPOSE STRONG CHANCE OF SERIOUS DEFECT YES 171 79 250 NO 36 35 71 Total 207 114 321

 NOT MARRIED * FAVOR OR OPPOSE DEATH PENALTY FOR MURDER Crosstabulation Count FAVOR OR OPPOSE DEATH PENALTY FOR MURDER Total FAVOR OPPOSE NOT MARRIED YES 111 51 162 NO 98 66 164 Total 209 117 326

______

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?

__171/207 – 79/114) = 13.31%______________

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?

________(111/209 – 51/117) = 9.5%________________

a.       Is this bigger or smaller than the above epsilon?

____smaller ______

b.      What does this mean?

_There is a weaker relationship among single mothers and opposition or supporting capital punishment then the first one. ________

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, and then find and interpret Lambda and Chi-Square values regarding the relationship between CAPPUN and POSTLIFE (believe in life after death) in the 2004gss_revised.sav file.

1.      State the Null Hypothesis and Alternative Hypothesis:

a.      Null Hypothesis (Ho):           __________

b.      Alternative Hypothesis (Ha):  __________

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

a.      Independent variable: ________

b.      Dependent variable:   ________

3.      Run the crosstabulation according to the methods we have learned. Paste only the appropriate  tables here (i.e.: Lambda and Chi-Square tables):

____________

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

__________

5.      What is the value of Chi-Square? (Remember: you report 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? Elaborate you answer in plain English, as if you were presenting it to a non-statistician person.
