Shows how much variation or dispersion from the average exists, on the particlesâ€™ size distribution of a soil, in metric scale. Arithmetic mean size (1st ... more

Arithmetic mean is the sum of a collection of numbers divided by the number of numbers in the collection. The collection is often a set of results of an ... more

The variance measures how far a set of numbers of n equally likely values is spread out. A small variance indicates that the data tend to be very close to ... more

In probability and statistics, mean and expected value are used synonymously to refer to one measure of the central tendency either of a probability ... more

In orbital mechanics, mean motion (represented by n) is the angular speed required for a body to complete one orbit, assuming constant speed in a circular ... more
