Computational Problems (15 points)

For the following computational problems, use the exercise data set from Blackboard. Turn on weight_full. Type up your tables and answers to the below questions, print them and attach the printout to your exam.

14. Frequency table (4p)

1. Make a frequency table of the two variables "liberal/conservative rating of the Democratic Party" and "liberal/conservative rating of the Republican Party". (2p)
2. Do not copy the SPSS output but present your findings in a table that is nice to read for your readership. This also includes inserting a reference below the table. (1p)
   E.g.:
   
3. Interpret your findings – what can you see in the table? (1p)

15. Cross table (7)

1. Make a cross table between liberal/conservative self‐placement (row) and liberal/conservative rating of the Democratic Party (column). (2p)
2. Again, present your findings in a neatly arranged table to your readership. Display row percentages. (2p)
3. Interpret your findings: Do liberals and conservatives evaluate the Democratic Party in a similar way? What can you see in the table? (1p)
4. What is the correlation coefficient Pearson’s r for this relationship? Interpret the strength of this association as well as the direction. (2p)

16. Comparison of means (4p)

1. Do men and women differ in their liberal/conservative self‐placement? Compare the average self‐placement (mean) of men and women. (1p)
2. Is this difference statistically significant? Conduct a T‐test for independent samples. What is the Null‐Hypothesis in this test (1p)? What is the p‐value (1p)? What does this mean for the Null‐Hypothesis – can you reject the Null‐Hypothesis at the 95% confidence level (1p)?
