Probability for normal distribution formula

WebbIf you want to calculate the probability for values falling between ranges of standard scores, calculate the percentile for each z-score and then subtract them. For example, the probability of a z-score between 0.40 and 0.65 equals the difference between the percentiles for z = 0.65 and z = 0.40.

Webb30 apr. 2024 · The normal distribution is a continuous probability distribution that is symmetrical around its mean, most of the observations cluster around the central peak, and the probabilities for values further away from the mean taper off equally in both directions. Extreme values in both tails of the distribution are similarly unlikely. Webb7 dec. 2024 · The formula used for calculating the normal distribution is: Where: μ is the mean of the distribution. σ2 is the variance, and x is the independent variable for which you want to evaluate the function.
