Independent variable. Apex
The variable that the experimenter deliberately changes is called the independent variable. The thing you are observing as a result of the different 'values' or 'conditions' of the independent variable is called the dependent variable. If the experiment is well controlled, then you can have some confidence that changes in the dependent variable have come about directly as a result of your changes to the independent variable.
Experimental variables are factors being tested or measured in a scientific experiment. They can be categorized as independent variables (manipulated by the experimenter), dependent variables (respond to the changes in the independent variable), and controlled variables (kept constant to prevent interference).
Microevolution can be studied by observing changes in the numbers and types of alleles, or genetics, in populations.
An artificial situation created by a scientist to observe the consequences of specific changes is called an experiment. In an experiment, the scientist manipulates variables to test hypotheses and determine the impact of those changes under controlled conditions. This method allows for the identification of cause-and-effect relationships in the natural world.
Chemical and physical changes are part of methods applied in science.
The independent variable is the thing the experimenter deliberately changes while observing the effects on the dependent variable.

The independent variable is the thing the experimenter deliberately changes or manipulates in order to observe its effect on the dependent variable in a scientific experiment.
The independent variable is the thing experimenter deliberately changes while observing in a scientific experiment. This variable is manipulated to observe its effect on the dependent variable, which is the outcome being measured.
The thing that the experimenter deliberately changes while observing is called the independent variable. This variable is intentionally manipulated to observe its effect on the dependent variable, which is the outcome being measured in the experiment.
The independent variable.
The experimenter deliberately changes the independent variable, which is the factor that is manipulated or controlled in an experiment to observe its effect on the dependent variable. This allows the experimenter to determine the causal relationship between the independent and dependent variables.

The independent variable.
The independent variable is the thing the experimenter deliberately changes to observe its effect on the dependent variable. It is manipulated to see if it causes a change in the outcome being measured.

The variable that the experimenter deliberately changes across groups is the independent variable. This variable is manipulated to observe the effect it has on another variable, known as the dependent variable.
