Explain meaning of term variability and normal distribution with examples.

Understanding Variability and Normal Distribution

Variability and normal distribution are essential concepts in statistics and probability theory that help us understand the dispersion of data points and the patterns of their distribution. Variability refers to the extent to which data points in a dataset deviate from the central tendency or mean. On the other hand, normal distribution, also known as Gaussian distribution or bell curve, is a specific type of probability distribution that describes the shape of data when it clusters around a central value. In this article, we will delve into these concepts and illustrate their meanings with real-life examples.
