hard📝 Application Q9 of 15
Step-by-Step Solution
Solution:
Step 1: Understand tie handling
Handling ties requires choosing an appropriate method for p-value calculation.Step 2: Check scipy methods
method='auto' lets scipy choose the best method considering ties and sample size.Final Answer:
method='auto' -> Option BQuick Check:
method='auto' handles ties best = A [OK]
Quick Trick: Use method='auto' to handle ties automatically [OK]
Common Mistakes:
MISTAKES- Using method='exact' which fails with ties
- Ignoring method parameter
- Confusing use_continuity with tie handling
