WebA normal distribution is continuous. A normal distribution is symmetric about its mean. The mean, median, and mode are equal for a normal distribution. The variance of normally distributed data is equally distributed about the mean. The graph forms a bell-shaped curve such that the maximum value is the mean. WebMean, median, and mode are different measures of center in a numerical data set. They each try to summarize a dataset with a single number to represent a "typical" data point from the dataset.
