What does 'Independent Variable' and 'Dependent Variable' mean | ||
|
The
cause variable, or the one that identifies forces or conditions that act
on something else, is the independent variable. The variable that is the
effect or is the result or outcome of another variable is the dependent
variable (also referred to as outcome variable or effect variable). The
independent variable is “independent of” prior causes that act on it,
whereas the dependent variable “depends on” the cause. It is not always
easy to determine whether a variable is independent or dependent. Two
questions help to identify the independent variable. First, does it come
before other variable in time? Second, if the variables occur at the
same time, does the researcher suggest that one variable has an impact
on another variable? Independent variables affect or have an impact on
other variables. When independent variable is present, the dependent
variable is also present, and with each unit of increase in the
independent variable, there is an increase or decrease in the dependent
variable also. In other words, the variance in dependent variable is
accounted for by the independent variable. Dependent variable is also
In statistical analysis a variable is identified by the symbol (X) for independent variable and by the symbol (Y) for the dependent variable. In the research vocabulary different labels have been associated with the independent and dependent variables like:
Independent variable Dependent variable Presumed cause presumed effect Stimulus Response Predicted from … Predicted to … Antecedent Consequence Manipulated Measured outcome Predictor Criterion
