  • Which variable is the variable you change?
    Independent Variable
  • Which variable is the variable you measure?
    dependent Variable
  • How would you describe this curve?
    Increasing at an increasing rate
  • Which variable is the variable you keep the same?
    Control Variable
  • Which variable goes on the y axis of a graph?
    Dependent Variable
  • How would you describe this curve?
    Decreasing at a Decreasing Rate
  • What is the definition of repeatable results?
    When the experimenter repeats the investigation using the same method, and gets the same results.
  • What is the definition of Systematic Error?
    An error that causes readings to differ from the true value by the same amount each time a measurement is made. Usually caused by a fault in equipment.
  • How do you calculate a mean?
    Add the values up and divide by how many values there are.
  • How would you describe this curve?
    Increasing at a decreasing rate
  • How would you describe this curve?
    Decreasing at an increasing rate
  • What is the definition of reproducible results?
    When the investigation is repeated by another person, using the same method, and gets the same results.
  • What is an anomaly?
    A value that looks out of place / does not fit the pattern in a set of results
  • In which type of average calculation do you exclude anomalous values?
    Mean
  • Which variable goes on the x axis of a graph?
    Independent Variable
  • What is the definition of a line of best fit?
    The line drawn to best represent the relationship between the independent and dependent variables. Can be a curve. Doesn't always pass through the origin.
  • Which type of error can have its effect reduced by taking repeats and calculating a mean?
    Random Error
  • What is the definition of Random Error?
    An error that causes readings to be spread about the true value, due to results varying in an unpredictable way from one measurement to the next.
