Many hypotheses have been proposed and tested.
Reading and educating yourself on the topic of study before you draw a hypothesis helps to reduce chances of a null hypothesis after the experiment. You draw the prediction conclusion from the accuracy of events that follow afterwards.
The ultimate value of a formalized hypothesis is it forces us to think about what results we should look for in an experiment. After a problem is identified, the scientist would typically conduct some research about the problem and then make a hypothesis about what will happen during his or her experiment.
Even the missing information that is unknown may get some hypothesis based on the knowledge you have of the topic. A Word From Verywell The hypothesis is a critical part of any scientific exploration.
Which is why scientists only support or not their hypothesis with data, rather than proving them. You may find many studies similar to yours have already been conducted.
