      At its core, the sigma equation formula (σ) calculates an inadequate quantity or process capability, representing the standard deviation of the population or the process variation from the desired target value. In simple terms, the sigma level of a process indicates its reliability and consistency, with higher sigma levels signifying greater control and lower sigma levels indicating higher probability of defects. To calculate the sigma value, you multiply the number of standard deviations by the z-score (standardized random variable). For instance, a z-score of 3 corresponds to 99.9% of the data lying within three standard deviations of the mean.
