WebJun 9, 2024 · A frequency distribution describes a specific sample or dataset. It’s the number of times each possible value of a variable occurs in the dataset. ... In graph form, a probability density function is a curve. You can determine the probability that a value will fall within a certain interval by calculating the area under the curve within that ... WebThe standard normal distribution is a normal distribution of standardized values called z-scores. A z-score is measured in units of the standard deviation. Definition: Z-Score. If X is a normally distributed random variable and X ∼ N(μ, σ), then the z -score is: z = x − μ σ.
