**Part 1: Interpreting Correlations**

A meta-analysis (Anderson & Bushman, 2001) reported that the average correlation between time spent playing video games (X) and engaging in aggressive behavior (Y) in a set of 21 well-controlled experimental studies was *r*+ = .19. This correlation was judged to be statistically significant. In your own words, what can you say about the nature of the relationship? Write a one-page response to this question.

**Part 2: Correlations**

You will use the following resources for this assessment. They are linked in the Resources, under the Required Resources heading.

- Complete this part of the assessment using the
**DAA Template.** - Read the
**SPSS Data Analysis Report Guidelines**for a more complete understanding of the DAA Template and how to format and organize your assessment. - Refer to
**IBM SPSS Step-By-Step Instructions: Correlations**for additional information on using SPSS for this assessment. - If necessary, review the
**Copy/Export Output Instructions**to refresh your memory on how to perform these tasks. As with your previous two assessments, your submission should be narrative with supporting statistical output (table and graphs) integrated into the narrative in the appropriate place (not all at th Read Moree end of the document).

You will analyze the following variables in the **grades.sav**data set:

- gender.
- gpa.
- total.
- final.

**Step 1: Write Section 1 of the DAA. DAA – Data Analysis and Application Template**

Provide a context of the **grades.sav** data set. Include a definition of the specified variables and corresponding scales of measurement. Indicate the type of correlation for each X, Y pair (for example, Pearson’s r, Spearman’s r, point-biserial r, et cetera). Specify the sample size of the data set.

**Step 2: Write Section 2 of the DAA.**

Test the assumptions of correlation for **gpa** and **final**. Paste the SPSS histogram output for each variable and discuss your visual interpretations. Paste SPSS descriptives output showing skewness and kurtosis values and interpret them. Paste SPSS scatter plot output with gpa set to the horizontal axis and final set to the vertical axis. Conduct a visual inspection of the scatter plot to analyze other assumptions of correlation. Summarize whether or not the assumptions of correlation are met.

**Step 3: Write Section 3 of the DAA .**

Specify a research question related to **gpa** and **final**. Articulate the null hypothesis and alternative hypothesis. Specify your alpha level.

**Step 4: Write Section 4 of the DAA.**

Paste the SPSS output of the intercorrelation matrix for all specified variables.

- First, report the
**lowest magnitude**correlation in the intercorrelation matrix, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Specify whether or not to reject the null hypothesis for this correlation. - Second, report the
**highest magnitude**correlation in the intercorrelation matrix, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Specify whether or not to reject the null hypothesis for this correlation. - Third, report the correlation between
**gpa**and**final**, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Analyze the correlation in terms of the null hypothesis

**Data Analysis and Application (DAA) Template**

Use this file for all assignments that require the DAA Template. Although the statistical tests will change from week to week, the basic organization and structure of the DAA remains the same. Update the title of the DAA. Remove this text and provide a brief introduction.

**Data File Description**

1. Describe the context of the data set. You may cite your previous description if the same data set is used from a previous assignment.

2. Specify the variables used in this DAA and the scale of measurement of each variable.

3. Specify sample size (*N*

**Testing Assumptions**

1. Articulate the assumptions of the statistical test.

2. Paste SPSS output that tests those assumptions and interpret them. Properly embed SPSS output where appropriate. Do not string all output together at the beginning of the section.

3. Summarize whether or not the assumptions are met. If assumptions are not met, discuss how to ameliorate violations of the assumptions.

**Research Question, Hypotheses, and Alpha Level (DAA – Data Analysis and Application Template)**

1. Articulate a research question relevant to the statistical test.

2. Articulate the null hypothesis and alternative hypothesis.

3. Specify the alpha level.

**Interpretation**

1. Paste SPSS output for an inferential statistic and report it. Properly embed SPSS output where appropriate. Do not string all output together at the beginning of the section.

2. Interpret statistical results against the null hypothesis.

**Conclusion**

1. State your conclusions.

2. Analyze strengths and limitations of the statistical test.
