The video tutorial explains different types of data distributions using examples. It starts with student height data, illustrating a normal distribution or bell curve, where data is symmetrically distributed around a central value. It then examines income distribution, showing a positively skewed distribution with a long tail on the right. Finally, it discusses negative skewness using student test scores, where the tail is on the left. The video highlights the differences between normal and skewed distributions, emphasizing the importance of understanding data distribution shapes.
