dependent variable
Constants or control variables are kept constant during an experiment to isolate the effect of the independent variable on the dependent variable. These variables do not change in order to ensure that any observed changes in the dependent variable are due to the manipulation of the independent variable and not influenced by other factors.
independent variable can be controlled by manipulation or selection.
The factors in an experiment that remain constant are called control variables. These are kept consistent to ensure that any changes observed in the dependent variable are due to the manipulation of the independent variable and not influenced by outside factors. Control variables help to isolate the effect of the independent variable on the dependent variable.
The manipulation of an independent variable during a scientific experiment allows a scientist to find a cause and effect relationship between variables. This is because the manipulation changes the results and measurements.
Experimenter variables are characteristics of the researcher that can influence the study outcomes, but are not typically used to measure manipulation in an experiment. Instead, manipulation is typically measured by the observed changes in the dependent variable(s) resulting from the experimental treatment or condition.
experiment
Albert Bandura is a social-cognitive theorist who argues that behavior is influenced by both situation variables and person variables. He proposed the concept of reciprocal determinism, which suggests that behavior is shaped by the interaction between personal factors, environmental factors, and behavior itself.
In a subroutine, the primary variables are parameters and local variables. Parameters are the inputs passed to the subroutine, allowing it to process specific data. Local variables are declared within the subroutine and are used for temporary storage of data during execution, remaining inaccessible outside the subroutine's scope. Together, these variables facilitate the subroutine's functionality and data manipulation.

In quantitative research, the most relevant aspect is typically the manipulation of independent variables to observe their effects on dependent variables. This approach allows researchers to establish causal relationships and analyze data statistically. By controlling and measuring these variables, quantitative research aims to produce reliable, objective findings that can be generalized to larger populations. Observational data can also be collected, but manipulation is key for testing hypotheses.
The variables in the activity included independent variables, which were manipulated to observe their effects; dependent variables, which were measured to assess changes; and controlled variables, which were kept constant to ensure a fair test. Additionally, external variables may have influenced the results and needed to be accounted for. Identifying these variables is crucial for understanding the outcomes and ensuring the validity of the experiment.
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.
