# Variable

A variable is a value that can change, depending on conditions or on information passed to the program. They are called variables because the represented information can vary. In mathematical terms, a variable is an algebraic symbol that represents a value that can change. Algebraic equations are a good example of the use of variables. In programming, variables can be used to hold data of many types, including numbers, characters and strings. What is the simple definition of variable? A variable is a value that can change, depending on conditions or on information passed to the program. What is a variable in statistics? In statistics, a variable is a value that can be measured or counted. Variables can be either categorical (e.g. gender) or numerical (e.g. age).

#### What is a variable in research?

A variable is something that can be measured or counted. In research, variables are often used to represent a characteristic of a population or a group of people. For example, age, gender, and income are all variables that can be used to describe a group of people.

#### What are the 3 types of variables?

1. Local variables are variables that are declared within a function, and can only be accessed within that function.

2. Global variables are variables that are declared outside of a function, and can be accessed by any function in the program.

3. Static variables are variables that retain their value between function calls.

### What is another word for variables?

There is no one-word answer to this question, as "variables" is already a pretty specific term in programming. However, some other words or phrases that could be used to describe variables in programming include:

-Data
-Values
-Inputs
-Arguments
