WebSep 3, 2024 · The term bell curve is used to describe the mathematical concept called normal distribution, sometimes referred to as Gaussian distribution. "Bell curve" refers to the bell shape that is created when a line is plotted using the data points for an item that meets the criteria of normal distribution. In a bell curve, the center contains the ... WebA z-table, also known as a standard normal table or unit normal table, is a table that consists of standardized values that are used to determine the probability that a given statistic is below, above, or between the standard normal distribution. A z-score of 0 indicates that the given point is identical to the mean. b0001-13 honda city WebJul 24, 2024 · The standard normal distribution not only has a mean of zero but also a median and mode of zero.

The standard normal distribution is a special normal distribution with a µ = 0 and σ = 1. We can use the Z-score to standardize any normal random variable, converting the x-values to Z-scores, thus allowing us to use probabilities from the standard normal table.
