What is the most appropriate conclusion?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceAn experimental conclusion states that the treatment increased the result by (10%). Which information is necessary to interpret this claim?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceIn an investigation a student examines the data first and then writes a hypothesis that fits those data. How should this be presented in the report?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceA scientific conclusion makes a claim broader than the data support.
