Practical Data Science using Python - Central Limit Theorem

The video tutorial covers the normal distribution curve, explaining how to calculate data proportions within standard deviations. It highlights the importance of understanding whether data is normally distributed and introduces tools like histograms and box plots for data visualization. The concept of percentiles is explained using box plots. The central limit theorem is discussed, emphasizing its assumptions and applications in statistics, particularly when dealing with non-normally distributed data.
