Independent variable. An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables). In experimental designs, the independent variables are manipulated by the researcher (e.g., different dosages of a drug).
an independent variable is the variable that u cannot control, such as time, volume, etc. dependent variable is the variable that depends on another variable. usually something like amount of rainfall or something. control variable is the variable that u can control...such as temperature, amount of heat, etc.
