It can be. If you are looking at the germination time under different conditions of temperature and humidity etc.
Manipulated variable is also known as the independent variable. The independent variable may determine if a seed germinates. Examples of manipulated variables for seed germination include: water, suitable temperature and air/oxygen. These basic variables are also the most important in seed germination.
In your investigation, the independent variable is the type of bird seed used, as it is the factor you are manipulating to observe its effect on the robins' preferences. You would need to vary the types of bird seed presented to the robins, such as sunflower seeds, millet, or mixed seeds, to determine which one they prefer. The dependent variable would be the robins' feeding behavior or preference, measured by the amount of each type of seed consumed.
The independent 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 is the one you control. The dependent variable is controlled by the 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.
Math: Independent variable is what you change. Dependent variable is what you measure.
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.
the anwer is a variable( the thng that will change over time in the experiment
An independent variable is a variable which stands independent and is unaffected by other variables. A dependent variable is a variable which is a response to the independent variable, and is usually the factor that is being tested in an experiment.
