To prepare for this Assignment, imagine that you have information about how 20 nursing students and 20 psychology students felt about starting PSYC 3002 on Day 1 of this class. You want to know if nursing students and psychology students felt differently about embarking on the Introduction to Basic Statistics journey. You can find the data set for this Assignment in the Weekly Data Set forum found in the Discussions area of the course navigation menu.

To complete this Assignment, submit your answers to the following. Use SPSS to determine if academic program is related to feelings about PSYC 3002 by computing the appropriate chi square test.

1. Recall the four scales of measurement you learned about in Week 1 (i.e., nominal, ordinal, interval, ratio). Explain what scale of measurement is used to measure academic program in this example. How do you know?
2. Explain what scale of measurement is used to measure feeling about PSYC 3002. Explain how you know.
3. State whether this scenario requires a goodness of fit test or a test of independence. Explain your answer.
4. Before computing the chi square, state the null hypothesis and alternative hypothesis in words (not formulas).
5. Identify the obtained χ2 using SPSS and report it in your answer document.
6. State the degrees of freedom and explain how you calculated it by hand.
7. Identify the p value using SPSS and report it in your answer document.
8. Explain whether you should retain or reject the null hypothesis and why.
9. Are the results statistically significant? How do you know?
10. Explain what you can determine about the relationship between academic program and feelings about PSYC 3002.

[U09a1] Unit 9 Assignment 1

Journal Article Summary

For this assignment, you will identify a published research article either in the print literature or online in the Capella Library. Your article must be based on empirical (data-based) research; qualitative or purely descriptive research is not appropriate. Select a journal article in your career specialization that reports a correlation, a t test, a one-way ANOVA, or some combination of these test statistics. The library guides listed in the Resources area can help you to locate appropriate articles.

The intent of this assignment is to:

• Expose you to professional literature in your discipline.
• Provide practice in the interpretation of statistical results contained in an empirical (data-based) journal article.
• Provide practice in writing and thinking in a concise and economical manner that is typical of scientific discourse.

You will summarize the article in a maximum of 600 words using the DAA Template located in the Resources area. Specific instructions for completing each section of the DAA Template are listed below.

You may use some of the author’s own words to summarize the article with proper citation, but avoid lengthy direct quotes (such as copying multiple sentences or paragraphs verbatim). You should not exceed the limit of 600 words. This is a situation where less is better.

Step 1: Write Section 1 of the DAA.

• Provide a brief summary of the journal article.
• Include a definition of the specified variables (predictor, outcome) and corresponding scales of measurement (nominal, continuous).
• Specify the sample size of the data set.
• Discuss why the journal article is relevant to your career specialization.

Step 2: Write Section 2 of the DAA.

• Discuss the assumptions of the statistical test used in the journal article.
  • If possible, identify information in the article about how these assumptions were tested.
  • If no information on assumptions is provided, consider this as a limitation of the reported study.

Step 3: Write Section 3 of the DAA.

• Specify the research question from the journal article.
• Articulate the null hypothesis and alternative hypothesis.

Step 4: Write Section 4 of the DAA.

• Report the results of the statistical test using proper APA guidelines. This includes:
  • The statistical notation (such as r, t, or F).
  • The degrees of freedom.
  • The statistical value of r, t, or F, and the p value.
• Report the effect size and interpretation if one is provided.
• Interpret the test statistic with regard to the null hypothesis.

Step 5: Write Section 5 of the DAA.

• Discuss the conclusions of the statistical test as it relates to the research question.
• Conclude with an analysis of the strengths and limitations of the study reported in the journal article.

Submit your DAA Template as an attached Word document in the assignment area.
