You've made the hypothesis that the less rainfall a cactus plant gets, the taller it will grow, since cactuses like dry conditio
ns. What should be the dependent variable in an experiment designed to test this hypothesis?
A. the height of the cactus plants
B. the hours of sunlight the cactus plants get
C. the amount of rain falling on the cactus plants
D. the type of soil the cactus plants are growing in
The dependent variable in this experiment designed to test this hypothesis is the height of the cactus plants.
In a hypothesis statement, we can always deduce the dependent and independent variables.
Independent variables do not rely on other variables. They are usually the cause of the phenomenon observed in an experiment. In this experiment, it is the rainfall on the cactus plant.
Dependent variable is that variable that relies on the independent variable. It is usually the effect of changes in independent variable.
The height of the cactus plant depends on the amount of rainfall in an area.
