Independent variable - temperature
Dependent variable - tablet dissolving affect.
Independent variable: Temperature
This is the variable that you, as the experimenter, are intentionally changing or manipulating. You are exploring how different temperatures impact the dependent variable.
Dependent variable: Tablet dissolving effect
This is the variable that you are measuring and observing. It is expected to change in response to the variations in the independent variable (temperature). In this case, you're investigating how the dissolution of the tablet is affected by different temperatures.
