Manipulation of the Independent Variable Again, manipulating an independent variable involves systematically altering its levels so that different groups of participants are exposed to different levels of that variable, or This means that the groups will be exposed to different levels at different times. Independent variables are variables that researchers manipulate to better understand how phenomena, structure, and behavior are related to the dependent variable and Alternative Hypothesis .
