In an experiment about how air temperature affects the amount of time it takes crocuses flowers to bloom, three crocus plants that had not yet bloomed were placed in three greenhouses with different temperatures.
What is the outcome variable (dependent variable) in this experiment?
the number of crocuses used
the amount of time it takes the crocuses to bloom
the air temperature
the greenhouses
The outcome variable (dependent variable) in this experiment is the amount of time it takes the crocuses to bloom.
This is because the dependent variable is what you are measuring in the experiment to see how it is affected by the independent variable, which in this case is the air temperature in the greenhouses. The blooming time depends on the temperature provided to the crocuses.
