The 20th percentile is an estimate of the value in which 20% of the observations should fall below this value and 80% should be above it. Methods vary on the calculations, but all methods will give similar results if there are a large number of values. See: http://en.wikipedia.org/wiki/Percentile

What does it mean when the doctor says that your baby weight is in the 20th percentile?

When a doctor says that your baby's weight is in the 20th percentile, it means that your baby weighs more than 20% of babies their age and less than 80% of them. This is part of a growth percentile scale that helps track development compared to a reference population. Being in the 20th percentile does not necessarily indicate a problem; it simply shows where your baby's weight falls relative to other babies. It's important to consider other factors, such as growth trends and overall health, when evaluating your baby's growth.

What is gre percentile vs score?

The GRE percentile indicates the percentage of test takers who scored lower than a specific score, providing a comparative measure of performance. For example, a 90th percentile rank means that a test taker scored better than 90% of all test takers. The GRE score itself is a numerical representation of a test taker's performance, typically ranging from 130 to 170 for the verbal and quantitative sections, while the analytical writing section is scored from 0 to 6. Thus, while the score reflects an individual's performance, the percentile contextualizes that performance relative to others.
