Step-by-Step Solution
Solution:
Step 1: Understand the purpose of chi-square test
The chi-square goodness of fit test compares observed data frequencies to expected frequencies to check if they match.Step 2: Identify what
This function calculates the chi-square statistic and p-value to evaluate the fit between observed and expected counts.scipy.stats.chisquaredoesFinal Answer:
How well observed data matches expected frequencies -> Option BQuick Check:
Goodness of fit = observed vs expected match [OK]
Quick Trick: Chi-square tests observed vs expected frequencies [OK]
Common Mistakes:
- Confusing goodness of fit with correlation
- Thinking it measures mean differences
- Mixing variance analysis with goodness of fit
