# What is a non-example of a variable?

That means finding something that changes, but isn't dependent on something else changing it. I would say that time is a non-example. It keeps changing regardless of how other things are changing. (Now, there is an exception to this in physics, where the passage of time changes in relation to velocity, but we're assuming that we are just talking about time as it is typically for us.) Another example would be something like a quantity purchased. Let's say that candy bars cost \$ .75 each. The total cost would be dependent on how many candy bars are purchased, so the total cost would be the dependent variable. The number of candy bars purchased would be the independent variable, since it doesn't depend (within reason) on the total price. Since it is an independent variable, it is not a dependent variable, so it is a non-example of a dependent variable. For example, someone could purchase either 3 or 4 candy bars, and the total price depends on how many are bought, but how many are bought doesn't depend on the total price. Study guides
