A variable is something that can be changed. In computer programming we use variables to store information that might change and can be used later in our program. For example, in a game a variable could be the current score of the player; we would add 1 to the variable whenever the player gained a point.

The best way to understand the difference between a dependent and independent variable is that the meaning of each is implied by what the words tell us about the variable you are using.

What is the definition of variable data?

Variable data is defined as information and figures used to build control charts. Variable data can be used to create average (X-bar) charts, range charts, and sample standard deviation charts or “S-charts.”

What is the difference between variable and data type?

A variable must have a data type associated with it, for example it can have data types like integer, decimal numbers, characters etc. The variable of type Integer stores integer values and a character type variable stores character value. The primary difference between various data types is their size in memory.

What is an example of variable data?

Variables data is data that is acquired through measurements, such as length, time, diameter, strength, weight, temperature, density, thickness, pressure, and height.
