    True value : The value of a parameter with absolute certainty is termed as its true value. Standard deviation : It is a measure of the spread or dispersion of a probability distribution. It reflects the degree of variation in measurement. With reference to Figure 7.1, standard deviation is given by. Normal or Gaussian Distribution : It
