What does an IQ of 81 mean?
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.
What if your test grades are 83 94 86 and 91 what grade fo you need to earn on your next test to have an average of 90?
An average is worked out by dividing the total of the scores by the number of scores. You have 4 scores already so when you have done the next test it will be 5 scores. If you multiply 5 scores by 90 it gives you a total score of 450. The 4 scores you already have adds up to a total of 354. If you subtract 354 from the 450 you get 96 and that is your target for the final test. The average for the first 4 tests comes out at 88.5
