    Example 1: A dart board

    Accuracy: i get most of my darts around the centre. Not necessarily close together.

    Precision: all my throws land in the exact same area (whether or not it is close to the centre)

    Example 2: Packets of Lollies

    The maufacturer claims each pack contains 20 lollies

    Accuracy: a sample of packets have 19,20,22,18,21,19,21 lollies. The average is 20. Accurate to the claim.

    Precision: a sample of packets have 18,17,17,17,18,18,17 lollies. Not accurate to the claim, but the values are constant.

    Example 3: An experimental result in a chemistry lab

    Doing an experiment, with five trials, the end results of the five trials for whatever is being tested are:

    35kg 36kg 33kg 35kg 36kg

    The actual value (as found in a scientific data book) is meant to be 42kg.

    From the results, the average value is 35kg. This is not at all accurate since the actual value should be 42kg. The results are precise however, since they do not vary from each other.

    In science, accuracy describes how close you are to the real answer; while a more precise answer is measured or calculated with more decimal places.

    For example if i really weigh 65.5 kg:

    an accurate measurement would be 66 kg

    a precise measurement would be 60.232103910

    an accurate and precise answer would be 65.500000

    hope that helps with your understanding...
