Question

Could someone help me understanding the definition of independent and dependant variables?

Answer 1

the independent is what changes and the dependent is what you are measuring

Answer 2

So if i was doing a science experiment on how plants react to being given different substances, the independant variable wouldnt be the plant?

Answer 3

no it would be the reaction , how did the plant change to the susbstance?

Answer 4

did it turn yellow, did it burn,etc

Answer 5

so the way the plant reacts is the independant variable?

Answer 6

In an experiment, the independent variable is the variable that is varied or manipulated by the researcher, and the dependent variable is the response that is measured

Answer 7

no ,the change that the plant had is the independent variable, what happened to the plant when the substances were added

Answer 8

isnt that the same as a reaction?

Answer 9

ok ok I think I have a perfect example
lets say that you want to demonstrate that by mixing pink and blue you get purple
the independent variable would be the purple because it changed during the experiment

Answer 10

ok so that makes sense.. but since i am actually doing an experiment on the plant thing XD im still confused on how i would explain the independent varible (in this case)

Answer 11

oh wow xD well a least you got it and with the plant you just have to write if the plant actually changed when you added the susbtance

Answer 12

directly after i added it? or at the end of the experiment

Answer 13

after you added it

Answer 14

you are going to write down if it changed,
example :the plant burned during the experiment

Answer 15

so when it asks, "What is the independant variable?" i say nothing? XD

Answer 16

example: the plant turned yellow when added this certain substance

Answer 17

well did it change?

Answer 18

so i see how that would work.. but im not adding acid or dry ice XD im using orange juice and vinager and stuff XD so it didnt change immediately

Answer 19

what changes are the substances

Answer 20
