# What is an independent variable?

Variables are, in the field of mathematics, symbols that appear in a function, a formula, a proposition or an algorithm. Its main characteristic is the ability to adopt different values.

When the value of one quantity depends exclusively on the value of another quantity, a mathematical function is established. This second magnitude, which determines the value of the first, is called the independent variable. Instead, the quantity whose value depends on the other acts as a dependent variable. It is important that we know that this term is composed of two words that, etymologically speaking, come from Latin:

-Variable derives from “variabilis”, which means that something can change its appearance and that it is composed of two distinct parts: the verb “variare” (change of appearance) and the suffix “-able”, which is used to indicate possibility .

-Independent, on the other hand, is the result of the union of three Latin components: the prefix “in”, which indicates negation; the verb “to depend”, which can be translated as “to be under the will of another”; and the suffix “-nte”, which is used to register the “agent”.

In addition to all the information we have provided about the aforementioned independent variable, it is necessary to know other data of interest such as these:

-When used in the domain of mathematics or statistics, it is represented by the “x”.

-In your case, it always develops on what is called the abscissa axis.

-Also in some sectors it is referred to as a manipulated variable.

– Characterized because arbitrary values ​​are assigned.
