Which of the following MOST directly influences a measurable outcome in an experiment? a. An independent variable b. A variable hypothesis c. A dependent variable d. Previous information

A). An independent variable

Explanation:

The Independent variable is characterized itself as the variable that is controlled or manipulated by the experimenter to observe its direct impact on the dependent variable. It is a variable that is not dependent and can stand alone. For example, if a student aims to observe the impact of temperature on solubility of a substance(sugar/salt) in a liquid, the temperature will be the independent variable as any change in the temperature will directly affect the solubility power of the liquid. Thus, option A is the correct answer.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
