ScienceIn which order should a strong scientific investigation be completed?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceA student deleted results that did not match the conclusion. How will this affect the experiment?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceIf the data show no clear trend what is the most appropriate conclusion?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceWhich experimental record would make replication easiest?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceAn experiment produced the expected result but had no control group. What is the main limitation of the conclusion?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceWhich type of result does not directly test a hypothesis?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceIf two experiments give the same average but one has less spread in its values which experiment is more precise?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceUnits were omitted from a data table in an experiment. What is the main consequence?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceWhich data would provide the strongest evidence against a hypothesis?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceAn experiment used very few samples and the results differed from one another. What should be said about the conclusion?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceIf an experimental hypothesis is vague what should be improved first?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceIn which situation would a causal conclusion be strongest?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceA student measured reaction time manually. What is the best way to improve the reliability of the results?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceWhat is the main benefit of random selection in an experiment?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceA student measured reaction rate at five temperatures but always tested from low to high temperature. What is a possible problem?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceIf the control group also shows the treatment effect what should be checked first?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceWhich option is the best example of an operational definition?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceThe values in an experiment show a very wide spread. Which step would be useful first?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceWhen results support a hypothesis which statement is most appropriate scientifically?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHardScienceWhy may enzyme activity results be affected if temperature is not controlled in an experiment?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard
