PSY 260 Module Two Activity Guidelines Graphing

Overview

This course will require you to create graphs using Microsoft Excel and the Analysis ToolPak add-in. For this activity, you will use the same data set as the Module Two Activity: Descriptive Statistics Quiz to create a pie chart and a histogram. This activity prepares you for creating graphs for Projects One and Three.

Note that you will submit images in your Soomo webtext of the two graphs you will create. This is important because you will need to do this again as part of Projects One and Three. For more information about how to save graphs as images, refer to the Save a Chart as a Picture resource from Microsoft Support.

Prompt

For this activity, you will submit a Word file containing two images of graphs: a pie chart for Race and a histogram for Age. You will complete this activity using your Soomo webtext writing template and the data set provided in Soomo.

Specifically, you must address the following:

1. Create a pie chart for Race.
2. Create a histogram for Age, with a bin for each year based on the minimum and maximum dataPSY 260 Project One Milestone Guidelines and Rubric

   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.
      1. 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.
      1. 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.
      1. 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.
      1. 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.
