Iq test how it works and why it s used

The IQ test is the common name for Intelligence Quotient. An IQ test is a way to measure the relative intelligence of a person, but the answers derived from an IQ test aren’t based on the amount of knowledge a person has. To fully understand how an IQ test works and why it’s useful, take a look at some facts (and myths) about IQ tests and testing methods.

An IQ test is not like a test that a student would take at the end of a particular class at school. If that were the case, the test would be fairly useless as a method of determining overall intelligence. At the end of a class, students have studied for those particular questions. Those who take an IQ test aren’t given a time to prepare for the test. Besides, that would merely be a test of a person’s ability to prepare for a test.

The idea behind IQ testing was to find a way to assign a number to a person’s intelligence. The IQ tests used to do this are a series of generic questions designed to test general understanding, comprehension and abilities as opposed to specific knowledge. To that end, questions such as “What year was the United States Constitution ratified” would not be part of an IQ test. That question tests a specific piece of information and it’s quite possible that even an intelligent person wouldn’t know the answer.

Instead, IQ tests require that the subject answer questions and perform simple tasks that anyone of their particular age level should be able to successfully complete.

There are many purposes for IQ testing. Children are often tested to help determine placement in particular classes. Deciding whether a child is in need of special education opportunities can be determined by using IQ tests. Developmentally delayed youngsters and adults can be monitored and placed based on IQ test results.

The results of an IQ test can be a signal of how adults will function in particular positions and situations. Employers sometimes use IQ test results to aid them in placement.

The use of IQ tests came under fire in recent years when opponents of this scale claimed that results were skewed for some subjects. Race, ethnicity and environment made some candidates score poorly on the test, despite their obvious intelligence, opponents said. There have been some efforts to correct those issues, but the fact is there’s no way to make a test that will be applicable for every subject.

Do you find it difficult to read try an audio book

There are many people who love fiction, but can’t read. Maybe you’re one of them. Some people can’t read for a physical reason – because they’re blind or have bad eyesight, for example – while some find reading difficult or strenuous on a mental level, such as dyslexic people and children. If any of these descriptions fit you, then maybe you should try audio books.

Audio books are voice recordings of people reading books – they used to be called ‘books on tape’, but now they mostly come on CD or even over the Internet as mp3 files. They are a surprisingly versatile medium, allowing for everything from straight readings to radio drama-style productions of the books with actors and sound effects. Some are read by the author, which can be an interesting experience, especially for books of poetry, while others are read by celebrities.

The best thing about audio books is that it’s much less effort to listen than it is to read. You can do other things while you have the audio book on, much like listening to music, such as driving or household chores. Audio books on long car journeys can be relaxing both for you and for children as well, as there are few things children love as much as hearing stories.

However, one word of warning. You should avoid any audio books you might find on the web that have been automatically produced by computer. The standard of computerised reading is not yet up to scratch for most purposes, and that’s certainly the case for audio books – it’s like hearing a robot trying to tell a story. The tone of voice is all wrong, the stresses go in the wrong place, and there’s no sense of drama. It’s difficult to even listen to for a long time, never mind enjoy. Until technology leaps forward (it’ll probably take a few decades), stick to human-read audio books.
