Different rose bushes are grown in a greenhouse for two months. The number of flowers on each bush is counted at the end of the experiment. What is the independent valuable? Dependent variable? Control variable?

Answer: The independent variable is type of rose bushes

The dependent variable is number of flowers

Control variable same greenhouse, same time period

Explanation:

The independent variable the factor of the experiment that does not depends on any other factor. The independent variable can be changed by the experimenter.

The dependent variable can be defined as the factor that depends on the independent variable.

Control variable can be defined as the factor which is kept constant during the whole experiment in order to get a clear relation between the independent variable and dependent variable.

The dependent variable would be the number of flowers on each bush

The independent variable is the greenhouse

The control variable is the two months (the timeframe)
