One will have to take 3 or more IQ tests ,in a clinical setting, to find ones average, but with a score of 81, the next two could be within a range of 15, add those up and divide by three and you have got your average IQ. However if one did the test online one might have had test anxiety, or was distracted and online tests don not give one a definitive answer and do not give ones total IQ score, such as a professional test.
