Theoretical mean formula
WebbThe Mean x ― = ∑ x N Here, ∑ represents the summation X represents observations N represents the number of observations . In the case where the data is presented in a tabular form, the following formula is used to compute the mean Mean = ∑f x / ∑f Where ∑f = N The Median WebbFormulas for the theoretical mean and standard deviation are μ = a + b 2 and σ = ( b − a) 2 12 For this problem, the theoretical mean and standard deviation are μ = 0 + 23 2 = …
