An independent variable is a variable believed to affect the dependent variable. This is the variable that you, the researcher, will manipulate to see if it makes the dependent variable change. In our example of hungry people throwing a ball, our independent variable is how long it's been since they've eaten.
A variable is anything that can vary, i.e. changed or be changed, such as memory, attention, time taken to perform a task, etc. Variable are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable. â¢ Independent variable (IV) : Variable the experimenter manipulates (i.e. changes) â assumed to have a direct effect on the dependent variable.
