They can, but errors on a paternity test are extremely rare. A test might prove inconclusive due to contamination, but it would not incorrectly point to someone who's not the father. * Such a matter would be decided by the judge presiding over the case. Actually it is not unusual for a judge to reorder a paternity test if there have been previous problems with the testing facility.
It necessary when performing an experiment that a large quantity of tests and trials are performed because observations tend to have errors. There are random errors, which are errors in measurement, and there are systematic errors, which are errors in procedure or calibration. Both have to be considered. Performing the experiment more than once allows one to estimate the varience of the results, to reject erroneous results, and to more accurately describe how the results fit the theory.
Other than WHICH errors!
Logic Error
These errors occur due to chance. These errors tend to cancel to each other in long run. These errors are random. They are not the results of any prejudice or bais.
One can learn facial exercises by watching YouTube videos. A video allows one to see how a facial exercise is actually performed to ensure that there are no errors made and the maximum results are achieved quickly.
This type of malformation results from trisomies.
Systematic Errors: Errors due to the design and execution of the experiment. They can be identified through a careful analysis of the experiment and associated experiments, and measures can be taken to correct them. Systematic errors occur with the same magnitude and sign every time the experiment is performed, and affect the accuracy of the results, but not the precision. If an experiment has small systematic errors, it is accurate. Random Errors: Errors due to indeterminate causes throughout the experiment, such as unpredictable mechanical and electrical fuctuations affecting the operation of the instrument or experimental apparatus or even human errors arising from psychological and physiological limitations. They occur with a different sign and magnitude each time an experiment is executed. If an experiment has small random errors, it is precise.
i really think it is to help you recognize what wrong with the experiment and improve your results
In order to minimize errors and confirm the results.
Semantic errors
The reason why it is necessary to monitor and record the results of works against programmes and schedules is to spot mistakes and errors.
The rate of false positive results for nicotine has not been established but false results can occur for a variety of reasons. Diet, medications, environment, and errors in the lab can cause false positive results on nicotine blood tests.
