ScienceIf a controlled variable gradually changes during an experiment what type of error may appear in the results?Class 9Exploration: Entering the World of Secondary ScienceVariables in an experimentHard ScienceIf a balance shows two grams more than the true value in every measurement what type of error is this?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceIn an experiment reaction time is measured using a mobile app. The app reads about (0.2) seconds too high in every measurement. What type of error is this?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceA student uses different uncalibrated thermometers for different groups. What is the main risk?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceIn which situation will repetition improve reliability but not validity?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationExpert ScienceEven after increasing the number of measurements all readings remain biased in the same wrong direction. What does this suggest?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceA student measures mass using two different balances and finds a constant difference between them. What is the most appropriate check?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceIf all measurements in an experiment are consistently two units above the true value what type of error is this?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceWhat is the main purpose of calibration in an experiment?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceIf all measurements in an experiment are consistently higher than the true value what is the most likely cause?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceWhich experimental change could improve accuracy without necessarily improving reliability?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceA thermometer reads two degrees above the true temperature every time. What type of error is this?Class 9Exploration: Entering the World of Secondary ScienceHypothesis and experimentationHard ScienceTwo thermometers consistently differ by two degrees in the same liquid. Which step is best for identifying the cause?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsExpert ScienceIn a weather study a rain gauge was placed under a tree. How might this affect the results?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsExpert ScienceTemperature was measured in an experiment but the thermometer calibration was not checked. Which quality may be affected most?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceIf all measurements in an experiment are consistently higher than the true value what type of error does this suggest?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceIf an instrument has an incorrect zero reading before an experiment what effect may occur on all measurements?Class 9Exploration: Entering the World of Secondary ScienceScientific questions and observationsHard ScienceAn instrument can measure very small differences but every reading has an error in the same direction. Which statement is correct?Class 9Exploration: Entering the World of Secondary ScienceNature and meaning of scienceExpert ScienceIf an instrument gives readings close to one another but always below the true value which description is correct?Class 9Exploration: Entering the World of Secondary ScienceNature and meaning of scienceExpert ScienceA result was obtained in several independent laboratories but all used the same faulty instrument model.
