The Fractionator Principle. The fractionator principle is one of the important concepts used in stereology. The importance of this principle cannot be overlooked. It appears in many different places. Although it looks different depending on how it is used, the principle is the same.
In mathematics, a variable whose value is determined by the value of an independent variable. For example, in the formula for the area of a circle, A = Ïr2, A is the dependent variable, as its value depends on the value of the radius (r). Compare independent variable.
Definition: A variable is a container that holds values that are used in a Java program. Every variable must be declared to use a data type. For example, a variable could be declared to use one of the eight primitive data types: byte, short, int, long, float, double, char or boolean. And, every variable must be given an initial value before it can be used. Examples: The variable myAge is declared to be an int data type and initialized to a value of 21.
