The true sigma in statistical terms represents the standard deviation of a population. It quantifies the amount of variation or dispersion in a set of values. A smaller sigma indicates that the values tend to be close to the mean, while a larger sigma indicates more spread-out data. In finance, sigma is used to measure market volatility. Knowing the true sigma helps in making more accurate predictions and informed decisions.
