The ozone leading to thicker-skinned animals and plants statement is not testable and refutable. In order for a statement to be a hypothesis it must be testable. In other words, we need to be able to make observations that will either support or refute the statement. While we may be able to speculate about what will happen if the ozone layer depletes, it would be very difficult to observe the gradual effects of ozone depletion on animals and plants. This statement is therefore an inappropriate scientific hypothesis. Therapy with drug A will decrease the symptoms of depression. This statement is both refutable and testable. The statement makes a positive prediction about the existence of something and thus is readily refutable. In addition, it would be relatively easy to observe the effectiveness of drug A on depressive symptoms thus the statement is testable. This statement is an appropriate scientific hypothesis.
