How are Stanford-Binet intelligence scale results measured?
.The test has a mean, or average, standard score of 100 and a standard deviation of 16 (subtests have a mean of 50 and a standard deviation of 8). The standard deviation indicates how far above or below the norm the subject's score is.
What percentage of children will score with in average range of IQ?
It depends to some extent on how you define "average". Most modern IQ tests are designed to give a normal distribution curve, meaning that 2/3 of the people will score within one standard deviation of the mean. (On the Stanford-Binet test, this means between 85 and 115).
What does an IQ of 135 mean?
Assuming that a score of 135 was earned on a test with a standard deviation of 15 (not 16 or 24) (e.g. Wechsler, as opposed to Stanford-Binet or Cattell), said score places one at the 99th percentile (assuming a mean score of 100; globally, mean IQ is approximately 88, circa 2015, placing a score of 135 above the 99.9th percentile [one per one-thousand people]). There are some intellectual (high-IQ) societies that accept only individuals who have scored at or above the top 1% (mean 100); the largest and oldest of these is Intertel.
What does an IQ score of 137 mean?
Attaining a score of 137 on a legitimate (psychologist-supervised) test (e.g. Stanford-Binet) with a standard deviation of 16 ranks one at the 99th percentile, objectively, assuming a mean score of 100. In reality, global mean IQ is ostensibly ~90 (SD16; 88, SD15); thusly, an SD16 score of 137 (SD15, 135) places one at approximately the 99.9th percentile amongst all people, worldwide. An individual scoring 137 (SD16) is eligible for admission to Intertel (and, of course, Mensa, given Mensa's lesser requirement of 132).
Is 135 a good IQ score for a 13 year old?
It depends on what kind of test you took. If it was a genuine IQ test with a mean of 100 and a standard deviation of 15 such as the Wechsler Intelligence Scale for Children or Wechsler Adult Intelligence Scale, administered and scored by a trained psychologist, then yes, that is an excellent score. The general public is strictly prohibited from having access to IQ tests such as the WISC, WAIS, or the Stanford-Binet. And so if you took this test online or obtained it from anywhere other than a psychologist, then it is guaranteed to be fake and your score is meaningless. Online so-called IQ tests generally have built in positive biases to give the test-taker a very high genius-level score, making them feel good about themselves, and encouraging them to part with their email address or credit card details in return for a "full analysis" that is completely made up.

What does an IQ score of 99 equate to?
That means just barely below average intelligence. An IQ score of 100 is considered to be average. So 99 would essentially mean average human intelligence.
Is 135 IQ good for a 13 year old?

Standard deviation is helpful in calculating?
Standard deviation is a calculation. It I used in statistical analysis of a group of data to determine the deviation (the difference) between one datum point and the average of the group.For instance, on Stanford-Binet IQ tests, the average (or, mean) score is 100, and the standard deviation is 15. 65% of people will be within a standard deviation of the mean and score between 85 and 115 (100-15 and 100+15), while 95% of people will be within 2 standard deviations (30 points) of the mean -- between 70 and 130.
