Fig trees, shrubs and lianas are found in the genus Ficus, which is a part of the fig or mulberry family (Moraceae). Most of them are found in the tropical regions of the world. There are some that can live in the warmer temperate areas. Many species may turn invasive in the right location.
Geometric mean. In mathematics, the geometric mean is a type of mean or average, which indicates the central tendency or typical value of a set of numbers by using the product of their values (as opposed to the arithmetic mean which uses their sum).
In fact even in mathematics there are different averages or means and this one is more properly called the arithmetic mean. The quantity obtained by adding the largest and smallest values and dividing by 2, statisticians call the midrange. There are times however that this is called the mean.
