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%...

Usually, new found data that contradicts a scientific theory isn't enough to discount the entire theory. Scientific theories get formed after many data by many people that support its formation. So one disagreeing datum or "evidence" usually won't disprove it. Another way to understand this: a...
The probability of rolling a number greater than 8 on one roll of a pair of dice is 0.277777.... Let's see how we get that probability, and, though it may be a little long winded, it's important to understand what's going on. With one roll of a pair of dice, we have 36 possible outcomes. They are 1...
Crude birth rate is how many live children are born. Crude death  rate is how many people die. Crude death minus crude birth is the  net gain (or loss) and is called the birth rate. It represents  whether or not deceased people are "replaced".
