      Clearly, you do not want to want to integrate the above probability density function. Unfortunately that function cannot be integrated in closed form. Luckily we have alternatives. First, we will “standardize” the data by subtracting the mean and dividing by the standard deviation. Do this for the data in C2, storing the results in C9:

      The probability density function (pdf) for the random variable x will be denoted f(x). The pdf gives the relative likelihood of different values of a continuous variable. For small dx, the probability density function is related to probability by (4.2) where f(x) has the units of 1/x.
