Question

What happens when the data in an investigation do not support the original hypothesis?

Answer 1

An hypothesis is an educated guess based on preliminary research. What should go next if the collected data doesn't support the hypothesis is to do a second experiment. If the second experiment does not support as well, the hypothesis should be changed because of the conclusion 

Answer 2

It's alright because a hypothesis is just a prediction and it is a guess that you make about what's gonna happen. Just make sure ur doing the investigation and recording the data correctly to get the accurate answer.
