In statistics and the social sciences, a percentile (or centile) is the value of a variable below which a certain percent of observations fall. For example, the 20th percentile is the value (or score) below which 20 percent of the observations may be found.
The term percentile and the related term percentile rank are often used in the reporting of scores from norm-referenced tests. Doctors often use a percentile calculator to assess an infant's weight and height percentile in comparison to national averages.
How much does your baby weigh, and how does that weight compare to other babies?
A Growth Percentile Calculator makes it easy to keep track of your child's growth and weight measurements as it can determine the percentiles for all children ages birth to 3 years old.
By using a Growth Percentile Calculator at home you can easily judge if your infant growing adequately and he or she is gaining weight and height at the normal rate. A percentile chart gives parents a good idea concerning how their baby's developmental progress compares with other babies nationwide of a similar age.
A percentile of 50% represents the average or mean weight.
A value below 50 percent means a baby weighs less than the average.
A value greater than 50 percent means a baby is above average.
This does not mean your baby is overweight or underweight. A doctor or physician should always be consulted to determine weight status.
This calculator provides your baby's weight percentile based on age, enter your infant's measurements into the Growth Percentile Calculator below to obtain all their percentiles based on infant growth charts. For example out of a sample of 100 babies, a percentile value of 45% means your baby weighs more than 45 babies and weighs less than the other 55 babies.
