Practical Data Science using Python - Random Variables and Normal Distribution

The video tutorial introduces the concept of random variables, using Usain Bolt's sprint times as an example. It explains the significance of normal distribution, also known as Gaussian distribution, in data science and machine learning. The tutorial further explores the application of the bell curve in performance management and appraisal ratings. Finally, it discusses the use of normal distribution in quality control, particularly in sampling and testing product batches.
