Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Susie wants to know if an increase in temperature is accelerating the decaying process of apples. What is the dependent variable (outcome variable) in this experiment?
A
the temperature
B
the appearance of the applesdependent
C
the acceleration
D
None of the above
Explanation: 

Detailed explanation-1: -In general, I would say that an apple will rot faster in warmer temperatures. Rotting is the result of bacteria and fungi growing in the food, as well as a series of chemical processes which occur after the fruit is picked. All of these processes are generally slowed down when it is cold.

Detailed explanation-2: -Independent Variable The independent variable is the one condition that you change in an experiment. Example: In an experiment measuring the effect of temperature on solubility, the independent variable is temperature. The dependent variable is the variable that you measure or observe.

Detailed explanation-3: -The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

Detailed explanation-4: -The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores since that is what is being measured.
