It depends on the experiment. It could be what the food is, the storage temperature, time, humidity or many other possible factors that affect spoilage.
Example: the amount of food is the independent variable because it has been changed and the growth of chickens is the dependent variable because the growth will be effected by the amount of food. Growth depends on the food
The independent variable.
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
An independent variable is a factor that doesn't rely on anything, unlike the dependent variable (which relies on the independent variable). The most common independent variable is time.
and independent variable is bigger than a dependent variable
The answer to your question depends on the experiment you are doing, but time would probably be the independent variable (and the amount of mold would be the dependent variable).
Example: the amount of food is the independent variable because it has been changed and the growth of chickens is the dependent variable because the growth will be effected by the amount of food. Growth depends on the food
factor effecting on food spoilage
The independent variable.
Independent, it is in the name, more variables are: dependant variable- the one you keep the same control variable- mearsuring variable
Changes in the independent variable are independent of changes in any other variable,
The independent variable.
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
The independent variable is called independent because it is the variable that is being manipulated or changed by the researcher to observe its effect on the dependent variable. It is independent of any other factors in the experiment because its values are determined by the researcher's actions.
Math: Independent variable is what you change. Dependent variable is what you measure.
