Read the attached articles and answer the attached questions.
The article (Pizzaro et al. 2007) should be used as Article 1. The article (Schreck et al. 2003) should be used as Article 2.
Article 1:
The selected article should contain Chi-square test(s) in a table or in text. If this article contains more than one Chi-square test, pick one and then answer the following questions.
1. What relationship is being tested in this Chi-square test? [2pts] Why is Chi-square test appropriate? [2pts]
2. How would you define this Chi-square test (e.g., 2×2, 2×3, etc.)? [1pt]
3. Interpret the result of this Chi-square test. In other words, did the authors find significant relationships between variables? Which relationships are significant, if any? What do these significant relationships tell you? [5pts]
Article 2:
1. Answer the following questions about the correlations based on the table that the authors present bivariate correlations:
a. Which is the strongest correlation in the entire table? Be sure to include the value of the correlation and describe the correlation (which variables are correlated). [2pts]
b. Which is the weakest correlation in the entire table? Be sure to include the value of the correlation and describe the correlation (which variables are correlated). [2pts]
c. Which variable(s) are consistently positively correlated with the criminological term you are interested in (e.g., crime, delinquency, sentencing length, etc.)? Interpret one positive relationship in sentence form (in the form of, as X increases, what happens to Y). [2pts]
d. Which variable(s) are consistently negatively correlated with the criminological term you are interested in (e.g., crime, delinquency, sentencing length, etc.)? Interpret one negative relationship in sentence form (in the form of, as X increases, what happens to Y). [2pts]
2. When researchers wish to report significant findings within a table, they often use asterisks. At the bottom of the table that presents bivariate correlations, you can see the note: * p < .05 for example. This note means that the authors performed a significance test on the correlations to determine if they had significant findings. They are telling us that all of the correlations with asterisks next to them were significant at the .05 alpha level. Using this information, answer the following questions about the correlations presented in the tables.
a. Are there any correlations that are statistically significant? Be sure to include the value of the correlations and describe the correlation (which variables are correlated). [3pts]
b. In this table, which variable(s) consistently demonstrate significant correlations with the criminological term you are interested in (e.g., crime, delinquency, sentencing length, etc.)? What do these significant correlations tell you? [4pts]
