Sentences with phrase «normal distribution»

The phrase "normal distribution" refers to a pattern or distribution of data that reveals a bell-shaped curve when plotted on a graph. In a normal distribution, the data is symmetrically distributed around the mean, meaning that most of the values cluster near the average, and fewer values are found towards the extremes. It is called "normal" because it is a common and frequently observed distribution in various fields, like statistics and natural phenomena. Full definition
