What is Percentile Rank ? Read in Details.


“Percentile” is in everyday use, but there is no universal definition for it. The most common definition of a percentile is a number where a certain percentage of scores fall below that number. You might know that you scored 67 out of 90 on a test. But that figure has no real meaning unless you know what percentile you fall into. If you know that your score is in the 90th percentile, that means you scored better than 90% of people who took the test.

Percentiles are commonly used to report scores in tests, like the SAT, GRE and LSAT. for example, the 70th percentile on the 2013 GRE was 156. That means if you scored 156 on the exam, your score was better than 70 percent of test takers.

The 25th percentile is also called the first quartile. The 50th percentile is generally the median (if you’re using the third definition—see below).
The 75th percentile is also called the third quartile.
The difference between the third and first quartiles is the interquartile range.

The delineation between system software such as and application software is not exact, however, and is occasionally the object of controversy. For example, one of the key questions in the trial was whether Microsoft's was part of its operating system or a separable piece of application software.

As another example, the is, in part, due to disagreement about the relationship between the and the operating systems built over this . In some types of , the application software and the operating system software maybe indistinguishable to the user, as in the case of software used to control a player. The above definitions may exclude some applications that may exist on some computers in large organizations. For an alternative definition of an app.

Some applications are available in versions for several different platforms; others only work on one and are thus called, for example. an application for Sometimes a new and popular application arises which only runs on one , increasing the desirability of that platform. This is called killer app. For example, VisiCalc was the first modern software for the Apple II and helped selling the then-new into offices. For Blackberry it was their software.

Teachers have the very important responsibility of shaping the lives of young, impressionable children. With this responsibility comes great pride and joy. Therefore all teachers should strive for what can be considered to be a "good teacher." A good teacher can be defined as someone who always pushes students to want to do their best while at the same time trying to make learning interesting as well as creative.

A positive or negative influence from a teacher early on in life can have a great effect on the life of a child. Teachers, especially at the elementary level, must be very creative with their teaching styles. Not every child learns the same way, nor are they interested in the same things. It is difficult to keep the attention of 15-20 children under the age of ten.

Classroom setup and design is a good way to get and keep the attention of students. Workstations are a good way to encourage different types of learning. By allowing children a chance to choose which activities they want to participate in, children are taking control of their own education. At the elementary level, children are always learning and sometimes don't even know it. When I was in kindergarten, I can remember playing at the different stations in the classroom. One station was for gardening and we could plant seeds and check them every day to see how much they had grown. Another station in that classroom that sticks out in my mind is the arts and crafts station. There was a large array of crayons, markers, scissors, construction paper and building materials we could use to make pretty decorations to give to our parents for our homes. By choosing which station we wanted to work at, we were becoming much more interested in what we were learning because we were doing what we wanted to do, not what we had to do. By setting high standards for a student, the teacher is encouraging the student to do the same and will eventually...
