☆☆☆☆☆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.
It is an experiment testing only ONE factor at a time. It's a test of the effect of a single variable by changing it while keeping all other variables the same, where every variable is planned and you have a hypothesis of what the outcome should be.
