easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Identify the correct function for independent samples
The function for independent samples isttest_ind, which takes two arrays as arguments.Step 2: Check the function call syntax
The correct syntax isstats.ttest_ind(a, b). Using only one array or the paired testttest_relis incorrect here.Final Answer:
stats.ttest_ind(a, b) -> Option AQuick Check:
Independent test with two arrays = stats.ttest_ind(a, b) [OK]
Quick Trick: Use ttest_ind for two arrays, both as arguments [OK]
Common Mistakes:
MISTAKES- Using ttest_rel for independent samples
- Passing only one array instead of two
- Forgetting to import scipy.stats correctly
