Percent error and percent uncertainty?

What does it mean when in an experiment the percent error and percent uncertainty are equal? When percent error is greater than percent uncertainty. When percent error is less than percent uncertainty. Thanks,

    Your percentage uncertainty is the percentage of random errors due to the accuracy of measurement. Your percentage error is the percentage of all errors in taking a measurement, including both systematic and random error.

    If your percentage uncertainty is equal to your percentage error it means there is no other source of error that the accuracy of the instrumentation used to take the measurement.

    If your percentage uncertainty is greater than your percentage error then it is likely you have made an error in calculating percentage error.

    If your percentage uncertainty is less than your percentage error this means there is likely to be some systematic error in the instrumentation making errors higher than the uncertainty.

    Enjoy :)
