What is 90th percentile out of 40?
For a complete definition of Percentile see the related link. A percentile is the value of a variable below which a certain percent of observations fallThe 90th percentile is typically the point at which 10 percent of the highest scores fall.If you assume that scores are out of 40, and that they are evenly distributed (an unlikely event in real life), then the 90th percentile is all scores above 36.

Growth chart?
Alternative NamesHeight and weight chartInformationGrowth charts are used to compare your child's height, weight, and head size against children of the same age.Growth charts can help both you and your health care provider follow your child as he or she grows. These charts may provide an early warning that your child has a medical problem.Growth charts were developed from information gained by measuring and weighing thousands of children. From these numbers, the national average weight and height for each age and gender were established.The lines or curves on growth charts tell how many other children in the United States weigh a certain amount at a certain age. For example, the weight on the 50th percentile line means that half of the children in the U.S. weigh more than that number and half of the children weigh less.WHAT GROWTH CHARTS MEASUREYour child's health care provider will measure the following during each well-child visit:Weight (measured in ounces and pounds, or grams and kilograms)Height (measured while lying down in children under age 3, and while standing up in children over age 3)Head circumference -- a measurement of the head size taken by wrapping a measuring tape around the back of the head above the eyebrowsBeginning at age 2, a child's body mass index (BMI) can be calculated. Height and weight are used to figure out the BMI. A BMI measurement can estimate a child's body fat.Each of your child's measurements is placed on the growth chart. These measurements are then compared with the standard (normal) range for children of the same gender and age. The same chart will be used as your child grows older.HOW TO UNDERSTAND A GROWTH CHARTMany parents worry if they learn that their child's height, weight, or head size is smaller than those of most other children the same age. They worry about whether their child will do well in school, or be able to keep up in sports.Learning a few important facts can make it easier for parents to understand what different measurements mean:Mistakes in measurement can happen, for example if the baby squirms on the scale.One measurement may not represent the big picture. For example, a toddler may lose weight after a bout of diarrhea, but will likely regain the weight after the illness is gone.Threre is a wide range for what is considered "normal." Just because your child is in the 15th percentile for weight (meaning 85 out of 100 children weigh more), this number rarely means your child is sick, you're not feeding your child enough, or your breast milk is not enough for your baby.Your child's measurements do not predict whether he or she will be tall, short, fat, or skinny as an adult.Some changes to your child's growth chart may worry your health care provider more than others:When one of your child's measurements stays below the 10th percentile or above the 90th percentile for his or her age.If the head is growing too slowly or too quickly when measured over time.When your child's measurement does not stay close to one line on the graph. For example, a health care provider may worry if a 6-month-old was in the 75th percentile, but then moved to the 25th percentile at 9 months, and dropped even lower at 12 months.Abonormal growth on the growth charts is only a sign of a possible problem. Your doctor will determine whether it is an actual medical problem, or whether your child's growth just needs to be watched carefully.See also:Failure to thriveHydrocephalusMicrocephalyShort statureReferencesKeane V.

What is the 90th percentile?
90th percentile is simple another way of saying that 9% scored above and 90% scored below (the other 1% being the number 90). For example, if you take a type of standardized test in high school, if you do well, you are at the 90th percentile, meaning 90% of students scored lower than you and 9% scored better. You can not be in the 100% percentile, because you cannot score better than yourself.

What is the IQ score when your percentile is 90?
The most reputable and widely used IQ tests used at present -- the individual (psychologist- or psychometrist-administered) WISC, WAIS, SB4 and SB5 -- are designed to have population average IQs of 100, with a standard deviation of 15. On such tests, the 90th percentile IQ is 119. On older individual and some group tests, the 90th percentile IQ may differ (usually, it is a bit higher -- 120 or 121). IQ scores and percentiles obtained from most online tests are not comparable to the individual IQ test results quoted here and should not be relied upon in clinical, employment-related, or educational situations. By the way, the IQ coinciding with 1 standard deviation above the mean is 115. An IQ of 115 is at the 84th percentile on the standard individual tests, and so must be considered a moderately high score. The 90% percentile score of 119 is at the lower limit of what might be considered a high, or clearly above average, IQ score. An IQ of 132 (98th percentile) or higher is required to join Mensa.
