Prior to beginning work on this discussion forum, read Chapter 2 of your textbook. Data visualization is the first step in communicating and displaying the results of data analysis. Commonly known data visualization techniques are tables and charts. Visualization techniques are selected based on the information that must be conveyed to the users. In your discussion,
Categorize situations where tables are a preferred visualization technique. Illustrate with an example.
Choose five different charting techniques that are available for visualization and compare. Explain why some are not suitable for displaying data and why others are more effective for data displays.
Explain Simpson’s paradox and provide an example different from the one listed in your textbook.
Tables are effective data visualization techniques when focusing on individual values. Tables are also significant when comparing pairs of values and not entire sets. The other specific means of visualizing data include area charts, box-and-whisker plots, bullet graphs, cartograms, and circle views. Techniques like charts are better because they display trends, while bar charts break down things simply by making them more effective. Simpson’s paradox refers to a statistical phenomenon where the relationship between two variables emerges, disappears, or reverses when the population splits into subpopulations.
