Language of measurement

• What is the purpose of control variables ?

  To ensure experiment is valid
• What is the issue with systematic errors ?

  affect reproducibility
• What does it mean is an experiment is repeatable ?

  repeated by the same person, same equipment and achieve the same results
• What reduces accuracy ?

  systematic and random errors
• accuracy = when a result is close to the true value
• precision = repeated results are clustered together
• What can repeating the experimennt help determine ?

  the precision of results
• reproducibility = the ability for a different person to repeat the experiment and get same results
