Scales of Measurement

Type text here. Discuss the implications of “scales of measurement” in quantitative research. Be sure to use a minimum of two citations to support your position(s). Be sure to review the “Scales of Measurement” media from Week 1. This section should be no more than two paragraphs.

Research Question

What are the means, standard deviations, frequencies, and percentages of the Lesson 21 Exercise File variables?

Presentation of Findings

I analyzed data from Lesson 21 Exercise File ⁴. In this section, I present descriptive statistics for the study quantitative and qualitative variables. Appropriate APA tables and figures accompany the analysis⁵.

Descriptive Statistics⁶

Descriptive statistics were run for the quantitative and qualitative variables in the Week 1 Assignment data set. Table 1 depicts the means and standard deviations for the quantitative data. Figure 1 depicts a histogram for the GPA variable. Table 2 depicts the frequencies and percentages for the qualitative (categorical) data. Figure 2 depicts a pie chart for the ethnic variable. Appendix 1 depicts the SPSS output.

1 Type your name here

2 Type in DDBA section number (e.g. DDBA 8307 – 6)

3 Enter faculty name here.

4 Insert the appropriate file name.

5 The tables and figures from your SPSS output will need to be copied and pasted in the appropriate location.

6 Detailed information can be found in Lesson 20, “Univariate Descriptive Statistics for Qualitative Variables,” and Lesson 21, “Univariate Descriptive Statistics for Quantitative Variables,” in the Green and Salkind text.

7This is an example of an APA-formatted descriptive statistics table. Refer to Sections 5.01-5.19, in the APA Manual for detailed information on APA tables. The descriptive statistics table here includes the appropriate information derived from the SPSS output that is to be pasted as an appendix. Do not split tables across pages. Note: The numbers in the SPSS output presented here are fictitious numbers and do not represent correct numbers in the data set you will use for this application.

8You would simply add rows to the table to accommodate the variables you have used in the analysis (i.e., variable 3, variable 4, etc.). Hint: Use the Microsoft Word Table feature.

9Recall from Lesson 20, “Univariate Descriptive Statistics for Qualitative Variables” (Green & Salkind, 2017), frequencies and percentages are reported for qualitative (nominal) variables. Note: Frequency and percentages are the only columns to be included.

10The pie chart is an appropriate graph for nominal (categorical) data.

11 You will copy-and-paste the appropriate SPSS output into the application assignment. See the document titled “Copying and Pasting SPSS Output into Word” located in this week’s Resources
