Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A boy waters one plant with fresh water and one with salt water and measures growth. What is the independent variable?
A
salt water
B
fresh water
C
growth of plants
D
None of the above
Explanation: 

Detailed explanation-1: -The independent variable is the amount of salt added to fresh water.

Detailed explanation-2: -It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.

Detailed explanation-3: -The amount of water is the independent variable because you are testing to see if water improves the growth of the plant. You are changing the amount of water given to each plant, so that you can see its effects on the plant.

Detailed explanation-4: -A dependent variable is what changes as a result of the independent variable manipulation in experiments. It’s what you’re interested in measuring, and it “depends” on your independent variable. In statistics, dependent variables are also called: Response variables (they respond to a change in another variable)

Detailed explanation-5: -The dependent variable is the variable that is being measured or tested in an experiment.
