It can be rejected if there is no control variable.
The dependent variable is the variable that can change in an experiment.
indeoendent variable
A factor that can be changed in an experiment is called an independent variable.
The factor changed is the independant varible, the thing that the scientist can change each time they run the experiment. The control is the part of the experiment that the scientist determines stays the same. Ex. They have one person eat a milk chocolate and a dark chocolate and then ask which one they like. The person is the control because it stays the same. The chocolate is the independant varible because the type changes.
control variable
It can be rejected if there is no control variable.
The variable is an experiment that is manipulated by the scientist. APEX
The dependent variable is the variable that can change in an experiment.
Control group or mean- it is the point to which variances will be compared
experimental variable
A manipulative variable is something that you will keep the same.

In a control, the scientists know what to expect what will happen in an experiment... it is used for comparison.A variable is pretty simple. All it is, is the thing in the experiment that changes. There is usually only one of them in an experiment, and there are two kinds... Im sure you are familiar with them.-An independent variable is when the scientist controls what they are looking for-A dependent variable scientists dont control directly, but they measure for results
