The dependent and independent variables are the two main variables in an experiment (National Library of Medicine, 2017) . A dependent variable is a variable that is being studied and measured in a scientific experiment, whereas an independent variable is a variable that is controlled or manipulated in a scientific investigation to evaluate the effects on the dependent variable. The independent variable affects the dependent variable in a dependent manner. The influence on the dependent variable is calculated and documented as the independent variable is advanced by the researcher. One other variable that is considered undesirable is the extraneous variable. Any variables that you are not specifically examining in your experiment or test are referred to as extraneous variables (Pourhoseingholi et al., 2012). Aiming to determine whether the independent variable has an impact on the dependent variable when conducting an experiment is the time that extraneous variables may be discovered. More often than not, these extraneous variables have never occurred to the researcher. Once you are aware of the unrelated factors influencing your investigation, you may choose a control strategy(Eads, 2021) . It is simple to decide which approach to utilize since each method corresponds to a certain group of variables. Among the techniques for control are: Random sampling: This technique takes into account participant characteristics and equally distributes the probability of selection. For instance, you may choose names at random to ensure that each participant has an equal chance of being assigned to either the control group or the experimental group. Masking: This technique involves experimenter variables. The double-blind procedure, sometimes referred to as masking, entails having the experiment be administered by a person who is blind to the study's goal. References: Eads, A.
