The elements of experiments include the independent variable (manipulated by the researcher), dependent variable (outcome being measured), control group (not exposed to the independent variable), and experimental group (exposed to the independent variable). Variables can be independent (controlled by the researcher), dependent (measured to see the effect of the independent variable), or extraneous (unintended variables that can affect the results).

Why do researchers use experiments rather than other research methods?
Researchers use experiments because they allow for cause-and-effect relationships to be established between variables. Experiments provide a high level of control over variables, which increases the internal validity of the study. This method helps researchers test hypotheses and make inferences about the relationship between variables.
Why do scientists use data from controlled experiments?
Scientists use data from controlled experiments to minimize the influence of outside factors, in order to isolate the effect of the variables they are studying. This helps to establish a cause-and-effect relationship between variables and ensures the results are more reliable and accurate.
What is a conceptual variable?
A conceptual variable is an abstract idea or construct that is used in research to represent a theoretical concept that cannot be directly observed or measured. It often serves as an underlying factor or theoretical explanation for observed phenomena in a research study.
What are the techniques to control the intervening variables?
One technique is to conduct experiments in a controlled environment where variables can be manipulated and controlled. Another technique is using statistical methods such as regression analysis to account for the influence of potential intervening variables. Additionally, conducting multiple studies or using longitudinal designs can help to assess the consistency of results across different conditions and reduce the impact of intervening variables.
What are two research methods widely used by psychologists?
Two widely used research methods in psychology are experiments, which involve manipulating variables to observe their effects on behavior, and surveys, which involve collecting self-reported data from participants to analyze relationships between variables.
What is the part of a science experiment that changes - called?
Elements of scientific experiments that are different from the controls, are called independent variables.
What are the variables found in all experiments?
independent and dependent variables
Factors that change in experiments are called?

What are some science experiments with variables?
