As an experimenter, would you want to have more or less repeated trials? Explain why 15. You have just complete analysis of data in an experiment and have concluded the data and qualitative observations were correctly gathered and they suggest the hypothesis is incorrect. What would be the next step. a. change the data to make the hypothesis correct. b. there is no next step, the experiment failed. c. review all observations and suggest a different hypothesis d. redo the same experiment over until you get the right data
