subject variable
the variable age has discriptive value but not necessarily explanatory value.
The independent variable is the thing you change, the dependent variable is the variable that changes because of the independent variable, it could also be referred to as the effect, and the control group is the constant, the thing that stays the same and the variable that you compare your results to.
The dependent variable would be blood pressure. The independent variable would be age. Of course, there are many factors, other than just age, which determine blood pressure.
yes
it is when a bunch of variable are put together in a group.
can a independent variable be changed in a group
a variable group is the group that a scientific supposes in a fact, but it needs to be tested/proven
The effect on the dependent variable will be different in the experimental group than the control group, which is why you measure the dependant variable.
In a controlled experiment, the experimental group is the group that has one variable changed.
The Control Group is not exposed to the tested variable.
Experiments typically involve:1) Experimental group: the group of subjects exposed to the variable being tested.2) Control group: should be as identical as possible to the experimental group, but is deliberately not exposed to the experimental variable - this provides a baseline measure from which the effect of the variable can be determined.

The Control(Controlled Variable)
In an experiment with frogs, no, the age of the frog is not a control variable. Instead it is an independent variable,or something you change.
