faiqraees · Answer

there are two variables brand fertilizer and plant growth 
it has been told in the question that brand fertilizer affects plant growth which means that a change in brand fertilizer can induce a change in plant growth 
So the independent variable is brand fertilizer since we can control it. We can change it to any type in just one go
So the dependent variable should be.....?
