A normal distribution is a symmetrical, bell-shaped distribution of data. If a variable is normally distributed in the data sample then it is generally assumed that the data will be normally distributed as well. The bell-shape of the normal distribution is based on a mathematical formula, with the variables scores increasing in size as you move from left to right of the horizontal axis (the X axis). The ...
