ScienceA student's conclusion is based only on the mean although individual measurements vary widely. What additional information is most needed?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceIn a comparison one group of plants was taller even before the treatment began. What is the appropriate analysis?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceIf an experimental result contradicts the hypothesis what should the scientist do first?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceWhat is the most appropriate action when an outlier appears in an experiment?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceIf experimental results do not support a hypothesis what should a scientist do first?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceIn which situation would percentage change be more useful than comparing final values?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceIn which situation can an average result be misleading?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceIf plants have very different initial heights in an experiment what is the most appropriate analysis?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceA student tests a treatment on four groups but bases the conclusion only on the group showing the largest effect. What is the most appropriate improvement?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceIn which situation can calculating the mean be misleading?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceA student concludes that fertilizer increases plant growth because the treatment group was taller on average. What else is needed to strengthen the conclusion?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceIn which order should a strong scientific investigation be completed?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceWhat should be confirmed before calculating an average in an experiment?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceWhich type of graph is most suitable for showing a continuous relationship between independent and dependent variables?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceIn five timing trials one value is much higher than all the others.
