SciPy - Statistical Tests
You want to compare a sample's distribution to a theoretical normal distribution using scipy. Which function and approach should you use?
You want to compare a sample's distribution to a theoretical normal distribution using scipy. Which function and approach should you use?
hard📝 Application Q9 of 15
Step-by-Step Solution
Solution:
Step 1: Identify one-sample KS test function
scipy.stats.kstest tests if a sample matches a given theoretical distribution.Step 2: Use 'norm' for normal distribution
Passing 'norm' as the distribution argument tests if sample fits normal distribution.Final Answer:
Use scipy.stats.kstest with the sample and 'norm' as the distribution -> Option BQuick Check:
kstest tests sample vs theoretical distribution [OK]
Quick Trick: Use kstest(sample, 'norm') to test normality [OK]
Common Mistakes:
MISTAKES- Using ks_2samp for one-sample test
- Confusing t-test with KS test
- Trying to pass two samples to kstest
