WebbBinomial Distribution The binomial distribution describes the number of times a particular event occurs in a ﬁxed number of trials, such as the number of heads in 10 ﬂips of a coin or the number of defective items out of 50 items chosen. The three conditions underlying the binomial distribution are: 1. Webb23 okt. 2024 · In a normal distribution, data is symmetrically distributed with no skew. When plotted on a graph, the data follows a bell shape, with most values clustering around a central region and tapering off as they go further away from the center. Normal distributions are also called Gaussian distributions or bell curves because of their shape.
