4. Quick Check:

   Tableau = fast, clear visuals, no coding [OK]

Hint: Remember: Tableau = fast visuals + no coding needed [OK]

Common Mistakes:

• Thinking Tableau needs coding skills
• Believing Tableau only works with small data
• Confusing Tableau with text-based tools

2. Which of the following is the correct way to describe Tableau's interactive features?

easy

A. Tableau's interactive features require complex coding.

B. Tableau only shows static images without interaction.

C. Tableau's interactivity is limited to changing colors.

D. Tableau allows users to explore data by clicking and filtering easily.

Solution

1. Step 1: Identify Tableau's interactivity

   Tableau lets users click, filter, and drill down into data easily.

2. Step 2: Match options to this fact

   Tableau allows users to explore data by clicking and filtering easily. correctly describes this; others are false or too limited.

3. Final Answer:

   Tableau allows users to explore data by clicking and filtering easily. -> Option D

4. Quick Check:

   Interactivity = clicking + filtering [OK]

Hint: Interactivity means easy clicking and filtering [OK]

Common Mistakes:

• Assuming interactivity needs coding
• Thinking Tableau only shows static visuals
