Calculating the Air Quality Index. The AQI is calculated by converting measured pollutant concentrations to a uniform index which is based upon peer-reviewed scientific evidence of the health effects associated with a pollutant.
For a Discrete random variable, the variance Ï2 is calculated as: For a Continuous random variable, the variance Ï2 is calculated as: In both cases f(x) is the probability density function. The Standard Deviation Ï in both cases can be found by taking the square root of the variance.or a Discrete random variable, the variance Ï2 is calculated as: For a Continuous random variable, the variance Ï2 is calculated as: In both cases f(x) is the probability density function.
