I need it in question/ answer format

Each part has to have at least 500 words.

In this module, you analyzed a hypothetical demand analysis. In this activity, you will discuss the findings of your analysis.

Review Ammons, Chapter 26, Table 26.3 [XLSX file size 11.6 KB] and the related material in the text. There are consistently more calls for service than the number of officers on duty. Using this information, address the following questions:

  • Are the increased calls for service the result of a lack of available officers on duty? Why?
  • Propose a statistical method or concept to defend or support your position. 

M5D2: Parametric vs. Nonparametric Part 2

In this module, you were introduced to parametric and nonparametric statistical tests. In this activity, you will discuss the differences between the two. 

For this activity, review the following article:

Bettany-Saltikov, J., & Whittaker, V. J. (2014). Selecting the most appropriate inferential statistical test for your quantitative research study (Links to an external site.)Links to an external site.. Journal of Clinical Nursing, 23(11/12), pp. 1520-1531. Retrieved from

Then, respond to the following:

  • Compare and contrast the difference between parametric and nonparametric tests.
  • Propose a scenario in which you would use the Chi-Square test instead of the Pearson’s R. Identify and classify your variables as well as the scale of measurement to justify your proposal.
