There are other statistical measures that should not be confused ... . For a real valued random variable X , the mean is the expectation operator expectation of X . Note that not every probability distribution has a defined mean or variance see the Cauchy distribution for an example. For a data set , the mean is the sum of the values divided by the number of values. The mean of a set of numbers x sub 1 sub , x sub 2 sub , ..., x sub n sub is typically denoted by math bar x math , pronounced x bar . This mean is a type of arithmetic mean.

The grand mean is the mean of the means of several subsamples. ref Everitt,2002 ref For example, consider several lots, each containing several items. The items from each lot are sampling statistics sampled for a Measurement measure of some variable and the means of the measurements from each lot are computed. The mean of the measures from each lot constitute the subsample mean. The mean of these subsample means is then the grand mean. Example Bob is interested in determining which American states have the tallest people. To do so Bob measures the height of a suitably sized sample of individuals in each state, separating individuals into groups by gender. Next Bob calculates the respective means for each state, and finally the grand mean for each gender with the corresponding standard deviation . Now Bob has the necessary information for a preliminary determination of which states have abnormally tall or short individuals by comparing the means of each state to the grand mean the standard deviation.

In celestial mechanics , the mean anomaly is a parameter relating position and time for a body moving in a Kepler orbit . It is based on the fact that equal areas are swept at the focus in equal intervals of time. The mean anomaly increases uniformly from 0 to math 2 pi math radians during each orbit. However, it is not an angle. Due to Kepler laws Kepler s second law , the mean anomaly is proportional to the area swept by the focus geometry focus to body line since the last periapsis . The mean anomaly is usually denoted by the letter math M math , and is given by the formula math M n , t sqrt frac G M star m a 3 ,t math where n is the mean motion , a is the length of the orbit s semi major axis , math M star math and m are the orbiting masses, and G is the gravitational constant . The mean anomaly is the time since the last periapsis multiplied by the mean motion , and the mean motion is math 2 pi math divided by the orbital period duration of a full orbit . The mean anomaly is one of three angular parameters anomalies that define a position along an orbit the other two being the eccentric anomaly and the true anomaly . If the mean anomaly is known at any given instant, it can be calculated at any later or prior instant by simply adding or subtracting math sqrt frac G M star m a 3 , delta t math where math delta t math represents the time difference.
