Normal curve template excel
What is an example of a normal curve?
Normal curves are also called bell shaped curves. A "true" normal curve is when all measures of central tendency occur at the highest point in the curve. The normal curve is an important, strong, reoccurring phenomenon in psychology. An example of a normal distribution would be a frequency distribution of people's height.

What is the standard normal curve?
The standard normal curve is a reference or a benchmark for many important concepts in statistics. It’s important because a lot of variables we see around like age, weight, height, etc form a standard normal curve. (e.g. majority of a class would be average performers while few would be high or low)
