Dependent variables
In an investigation, the three primary variables are independent variables, dependent variables, and controlled variables. The independent variable is the factor that is manipulated or changed to observe its effects. The dependent variable is the outcome or response that is measured to determine the impact of the independent variable. Controlled variables are the conditions kept constant throughout the investigation to ensure that any changes in the dependent variable are solely due to the manipulation of the independent variable.
As many as are necessary, as few as possible.
In an investigation, the three types of variables are independent, dependent, and controlled variables. The independent variable is the one that is manipulated or changed by the researcher to observe its effect. The dependent variable is the outcome that is measured to see if it is influenced by changes in the independent variable. Controlled variables are constants that are kept the same throughout the experiment to ensure that the results are due to the independent variable alone.
The independent variable in this investigation is the factor that is manipulated or changed deliberately by the researcher to observe its effects. The dependent variable is what is measured or observed in response to the changes made to the independent variable. Other variables, known as controlled or constant variables, are kept the same to ensure that any observed effects are due to the manipulation of the independent variable. In summary, the investigation compares the effects of the independent variable on the dependent variable while controlling other factors.

dependent variable
There can only be one independent and one dependent variable. All other variables should be classed as control variables and must be kept constant to achieve a fair test.
The variables under study typically refer to the specific factors or characteristics that researchers are examining in a particular investigation. These can include independent variables, which are manipulated or changed, and dependent variables, which are measured to assess the effect of the independent variables. Additionally, there may be control variables that are kept constant to ensure that the results are due to the independent variables alone. Identifying and clearly defining these variables is crucial for the validity and reliability of the research findings.
time or length could be two different variables depending in what the investigation was based on
True. An independent variable is the factor that is intentionally manipulated or changed by the researcher in an experiment to observe its effect on a dependent variable. This distinction allows for the investigation of causal relationships between variables.
