What is a control variable? - CORRECT ANSWERS-Something that must be kept
constant to prevent it affecting the dependent variable
What is meant by the repeatability of results? - CORRECT ANSWERS-Similar results
would be obtained from repeats of the same measurement from the same experimental
set up.

would be obtained from repeats by different people with different equipment.
How can you ensure a metre rule is held vertically? - CORRECT ANSWERS-Use a
plumb line, set square or spirit level

scale are all in line with each other OR ensure object and scale are directly adjacent to
each other
What is meant by the term random error? - CORRECT ANSWERS-Errors that cause
the measurement to vary in unpredictable ways.
What is a systematic error? - CORRECT ANSWERS-An error that causes the
measurements to differ from the true value by a consistent amount.
