WebbNormal Distribution - General Formula. The general formula for the normal distribution is. f ( x) = 1 σ 2 π ⋅ e ( x − μ) 2 − 2 σ 2. where. σ (“sigma”) is a population standard deviation; μ (“mu”) is a population mean; x is a value or test statistic; e is … Webb5 nov. 2024 · x – M = 1380 − 1150 = 230. Step 2: Divide the difference by the standard deviation. SD = 150. z = 230 ÷ 150 = 1.53. The z score for a value of 1380 is 1.53. That means 1380 is 1.53 standard deviations from the mean of your distribution. Next, we can find the probability of this score using a z table.

Webb6 mars 2024 · The two main parameters of a (normal) distribution are the mean and standard deviation. The parameters determine the shape and probabilities of the distribution.
