Max wants to see if mice that are fed food a grow faster than mice that are fed food b. he measures the mass of the mice each day. he feeds each group the same amount of food at the same time each day. what is the dependent variable?

The dependent variable is the mass of the mice.

The dependent variable in the case above is the mass of the mice.

Further explanation

A variable is an object that we are trying to measure. In the experiment, there are two kinds of variables, dependent and independent variable.  

The dependent variable is the variable that is being measured or tested. These dependent variables depend on other factors. In the case above, the mass of the mice is a dependent variable. This mice's mass depends on other factors, which is the food they are given. This mice's mass would be change depend on the type and how much food they are given. Independent variable clearly stated on the name. Independent means that the variable does not depend on other factors. It is not changed by the other variables you are trying to measure, but the independent variable causes a change in a dependent variable. For example, someone's age, It does not change even when the other variable change such as the food they eat and how much television program they watched. Learn more
