   The result field is numeric but placed in 'Explain by' instead of 'Analyze' explains a common setup error causing no influencers to appear.

3. Final Answer:

   The result field is numeric but placed in 'Explain by' instead of 'Analyze' -> Option C

4. Quick Check:

   Result field must be in Analyze [OK]

Hint: Put result in Analyze, not Explain by [OK]

Common Mistakes:

2. Step 2: Assign factors to explain churn

   Age, Contract Type, and Monthly Charges are factors that might influence churn, so they go in 'Explain by'.

3. Final Answer:

   Put Churned in 'Analyze' and Age, Contract Type, Monthly Charges in 'Explain by' -> Option D

4. Quick Check:

   Result in Analyze, factors in Explain by = D [OK]

Hint: Put outcome in Analyze, factors in Explain by [OK]

Common Mistakes:

• Putting factors in Analyze instead of result
• Mixing up categorical and numeric fields incorrectly
• Placing all fields in one bucket
