A normal curve, also known as a bell curve or Gaussian distribution, is a statistical representation of the distribution of data. The shape of a normal curve is symmetrical, with the highest point in the center and the tails tapering off on either side. This type of curve is commonly used in statistics to represent the distribution of data that is normally distributed, such as heights of people or test scores.
To make a normal curve in Excel, you can use the NORMDIST function. This function takes several arguments, including the mean, standard deviation, and x-value. The mean is the average value of the data, the standard deviation is a measure of the spread of the data, and the x-value is the value for which you want to calculate the probability. For example, the following formula will create a normal curve with mean 0 and standard deviation 1:
