Something that changes during an experiment. A variable is something that is bound to change and not constant

In a mathematical statement a variable is something which can take on different values; it is usually represented by a letter, though a word could be used. Examples include: x + 5 (x is a variable) area_rectangle = lw = length × width (l, w, length and width are all variables), area_circle = πr² = π × radius² (r and radius are both variables)
Variable means that something is liable to change, is not constant. For instance, weather is very variable in Britain. Our weather can change hourly, with rain, sun, etc.
