In this project, we’ll use our unique IAT random samples to demonstrate what we learned in Unit 3 (Modules 7, 8, 9, & 10).
WARNING: Since this project is equivalent to an exam, I will not be able to help you. However, you can still rely on your classmates for help, and I can answer clarification questions.
Progress Check Use this activity to assess whether you can: Use appropriate statistical data to describe a distribution.
Create an appropriate graph to compare a quantitative variable grouped by a categorical variable.
Recognize quartiles as the markers between four equally-sized groups within a distribution of data.
Describe the distribution of a quantitative variable grouped by a categorical variable using percentages and descriptions of center and spread to make comparisons.
Draw conclusions about the relationship between variables within the context of a given situation. Directions
WARNING: The directions for Unit Projects differ from the directions for homework and lab assignments.

Prompt
(Since this is your first unit project, here’s a little hint. The Unit 3 Project is very similar to the “Module 9: Comparing Boxplots Lab” assignment, In fact, every unit project is very similar to at least one – and often more than one – “homework” or “lab” assignment from that unit.)
To respond to the following items, use the quantitative variable and just one of the categorical variables listed above. You choose which categorical variable from the list above you want to analyze.
Use concepts from Unit 3 to describe the distribution of the quantitative variable grouped by the categorical variable. Then make comparisons and draw conclusions.Make an appropriate graph and provide appropriate numerical summaries.
Embed your StatCrunch graph in your response, and be sure to include the Alt Text. Complete each of the following to make the graph more meaningful to the reader.Include a meaningful title above your graph.
Underneath your graph, describe the variables represented in the graph.
Below your graph, provide a key for the numerical category labels in your graph. Hint: see the category descriptions for your categorical variable in the variable descriptions list for your IAT data set above.
Copy and paste the StatCrunch table of numerical summaries into your response.To make it easier for the reader to understand your table, replace any numerical category labels with meaningful words. Hint: see the category descriptions for your categorical variable in the variable descriptions list for your IAT data set above.
Choose two or three groups of the categorical variable that are most interesting to compare. Then use percentages and descriptions of center and spread to make comparisons. What do the data suggest? For example, is a particular group from the categorical variable more likely to have a higher/lower IAT score?Use the data to support your answer.
Interpret the result in context. Hint: to learn how to interpret the IAT score, see the variable descriptions link for your IAT data set (included in the Variables section above).

This criterion is linked to a Learning OutcomeSelf-EvaluationThe final draft begins with a self-evaluation of your first draft. The self-evaluation describes how you demonstrated attainment of the learning objectives in the “Progress Check” section of the assignment, OR what you needed to correct in order to demonstrate attainment of the learning objectives.
5 ptsComplete
3 ptsPartial Credit
The self-evaluation does not describe how you demonstrated attainment of the learning objectives in the “Progress Check” section of the assignment, or what you needed to correct in order to demonstrate attainment of the learning objectives.
0 ptsIncomplete
No self-evaluation of your first draft is included with your final draft. Or, you did not commit a good-faith effort on your first draft and therefore your self-evaluation is not applicable.
