      F(x) = P(X < x) • This is when X is a continuous r.v. Example: If X is a normal variable with mean 100, its c.d.f. F(x) should look like: • Sometimes we do not know the distribution of our variable of interest. • The empirical distribution function (e.d.f.) is an estimator of the true c.d.f. – it can be calculated from the sample data.

      and if the x and y are independent, then f(x,y) = f(x). 4.3 Mean, Median, and Mode . There are three different measures of an “average” that are commonly used in seismic hazard analyses: mean, median, and mode. In general, these three different measures of “average” do not lead to the same value. The normal distribution is a special ...

      If the data is a table of frequencies (or relative frequencies) the sample mean is computed as: where f(x) is the relative frequency for the specific value of X and P(x) is the probability that the specific value of X will occur. Another notation for P(x) is P(X = x), where the uppercase X represents the characteristic being measured (e.g ...

      By: Neil E. Cotter Probability Mean/expected value Mean = center of mass Example 1 Ex: A probability density function, f(X), is shown below. Use the center of mass method to find E(X), the expected value of X. Sol'n: When parts of f(X) are horizontally symmetrical, we can replace them with a point mass located at their center of mass.
