Detailed explanation-1: -Normal distributions come up time and time again in statistics. A normal distribution has some interesting properties: it has a bell shape, the mean and median are equal, and 68% of the data falls within 1 standard deviation.

Detailed explanation-2: -A normal distribution is a true symmetric distribution of observed values. When a histogram is constructed on values that are normally distributed, the shape of columns form a symmetrical bell shape. This is why this distribution is also known as a ‘normal curve’ or ‘bell curve’.

Detailed explanation-3: -A bell curve is a graph that is a normal distribution. The graph is a bell-shaped line where the curve’s highest point shows the most probable event in a number (or series) of data.

Detailed explanation-4: -A bell curve is referred to as a normal distribution because it is the most common type of distribution for a variable. The term bell curve’ is derived from the graph depicting a normal distribution because it consists of a bell-shaped line.
