Independent Variable
Independent variables are key components of research studies that are being manipulated to test their effects on dependent variables. In this context, independent variables are the phenomena or factors that researchers alter or change to observe their impact on the outcome of the study.
Independent variable: In research, this is the variable or phenomenon being manipulated in the study and is not dependent on changes in other variables.
- Example, in the study by Ghanbari et al. (1), the independent variable is "knee joint mobilization", the dependent variable is "quadriceps muscle strength."
