The Chi-Squared Test - Are Two Distributions the Same? with Python Example

Learn to determine whether two datasets originate from the same or different distributions using the Chi-squared statistical test through a comprehensive 23-minute tutorial. Explore this fundamental statistical question through a practical case study examining alpha emissions, where you'll understand the complete process from data collection to hypothesis testing. Master the creation of test statistics and hypothesis formulation before implementing the Chi-squared test in Python through hands-on coding demonstrations. Follow along as the tutorial progresses from theoretical foundations through a real-world alpha emissions example, covering process summary and data analysis, test statistic construction, hypothesis building, and practical Python implementation, concluding with a comprehensive summary of the Chi-squared testing methodology.
