explain the concept of 'normal distribution'
user
normal distribution is a probability distribution in which data is distributed evenly along a bell-shaped curve, with most data points near the mean and few at the extremes. it is also sometimes referred to as gaussian distribution, and is used in mathematics and statistics to model real-world observations such as heights, weights, iq scores, and test scores.
