Exam 2 will focus on refining Tableau charts. This builds on concepts from Exam 1 but layers on more advanced techniques and a stronger emphasis on style. You will be given a Tableau workbook containing charts with some problems, and your task will be to identify and fix those issues to create a more effective visualization.
Practice:
You should be able to complete the following tasks in Tableau.
Beyond technical skills, you should also be able to apply the following style guidelines to your work. This relates to taste, figuring out what works well and looks good to a user.
You are not going to be tested directly on the visual perception concepts in this exam (though they will show up later). Instead, you should understand how these concepts apply to your work in Tableau.
For example, you should understand avoid using too many categorical colors (which would break Miller’s Law), remove visual clutter, or fix an axis to avoid breaking the principle of proportionality.
