2-4 Project One Milestone

2-4 Project One Milestone

Q Overview As you learned in the Module Two Activity: Descriptive Statistics Quiz, thinking critically about your data and taking appropriate statistical approaches is what will enable you to perform the right calculations to draw appropriate conclusions. To prepare for Project One, in this milestone you will get to know your Project One data. This assignment will ensure that you are set up for success on your project, so make sure you review your instructor feedback thoroughly before submitting Project One, due in Module Four. Your textbook notes that scales (e.g., Likert-type scales) are often treated as if they are interval in applied statistics for the psychological and social sciences. This is true, and, as noted in your text, it is an area of debate even among those who do statistics regularly in these areas. We will, on occasion and for instructional purposes, follow this practice; however, for this assignment we want you to provide the most technically correct responses for all of these items—not indicate how data might be treated in practice. In your textbook, you learned that as scales of measurement become more numeric in nature, you have more options for measures of central tendency and variability because you can perform more mathematical operations. As you respond to the prompt, we would like you to select the measures of central tendency or variability that require the most mathematical computation that is reasonable to report, given the scale of measurement. For example, if your data were interval or ratio, you can report a mode, a median, or a mean, but the mean would be the measure of central tendency that requires the most mathematical computation. Thus, we would want you to report “Mean” as the answer for a variable measured on such a scale. Prompt For this milestone, you will submit a Word file. You will complete your milestone using your Soomo writing template and the data set provided in Soomo. Specifically, you must address the following rubric criteria: 1. Identify the scales of measurement for each variable. A. For the purpose of identifying scales of measurement, use (1) Nominal, (2) Ordinal, or (3) Interval and/or Ratio as accurately as possible. 2. Identify reasonable measures of central tendency, given the scales of measurement for each variable. A. For the purpose of identifying measures of central tendency, use (1) Mean, (2) Median, or (3) Mode. 3. Identify reasonable measures of variability, given the scales of measurement for each variable. A. For the purpose of identifying measures of variability, use (1) Range/Interquartile Range, (2) Standard Deviation/Variance, or (3) None. 4. Identify reasonable graphic depictions, given the scales of measurement for each variable. A. For the purpose of identifying graphic depictions, use (1) Bar/Pie or (2) Histogram. 5. Describe how these concepts intersect and why scales of measurement influence decisions about statistics and graphics. The length of your description must be about 4 to 7 sentences. Guidelines for Submission You will use your Soomo writing template to complete the milestone and download it for submission.

Within the information provided by calculating the averages for each column, these ideas cross paths. After that, you'll see a trend where dots meet to illustrate commonalities between each data set. We may choose the appropriate measure of central tendency by understanding the scale of measurement for a given collection of data. This also enables us to select the appropriate graphic and measure of variability. Scales of measurement have an impact on judgments about statistics and graphics since they determine the statistics we will employ based on the scale of measurement that is selected (Few & Edge, 2007). It employs the mean or median as well as the range and interquartile range for ordinal data. I
