Calculate the mean and standard deviationStephen Weigand
σ (sigma): Standard deviation symbol. xᵢ: Each number in your dataset. μ (mu): The average of your numbers. N: Total number of data points. What Does This Formula Mean? In simple terms, standard deviation is calculated by: Comparing each data point to the average (mean). Squaring...
? = standard deviation N = total number of elements Xi = ith element \mu = Mean of the given elements Therefore, in this article, we calculate the standard deviation of the given array by using the above mathematical formula. For example ? Arr = [2, 4, 5, 6, 7, 2] Standard devi...
