That question, this incomplete. The full question is:

3. Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. The heights of the trees are measured once a week. What are the dependent variables, independent and the controlled variable of this experiment?

Answer:

  • Independent variable: different humidity levels
  • Dependent variable: the heights of the trees
  • controlled variable: the types of trees

Explanation:

An independent variable is one that exerts an influence within the experiment and can be measured, acting on other elements to promote the observation of a result. As the experiment seeks to observe the influence of humidity on the height of the tree, we can say that humidity is the independent variable.

Dependent variable is that which is influenced by the independent variable to generate a result that can be observed, can also be measured. As the experiment wishes to analyze how the height of the trees was affected by the level of humidity, we can say that the height of the trees is the dependent variable.

Controlled variable is that which is present in the experiment in a constant and equal way, cannot be measured. This variable is the type of trees.
