Normal Distribution
Data is usually distributed in different ways w i th a bias to the left or to the right or it can all be jumbled up. However, there are chances that data is distributed around a central value without any bias to the left or right and reaches normal distribution in the form of a bell-shaped curve. The random variables are distributed in the form of a symmetrical, bell-shaped curve. Properties of Normal Distribution are as follows; Unimodal -one mode Symmetrical -left and right halves are mirror images Bell-shaped -maximum height (mode) at the mean Mean, Mode, and Median are all located in the center Asymptotic
