IQ, IQ Test and IQ Scores
You might have come across many different people already, and probably you might have noticed that there are people who can learn and master new skills pretty quickly, there are people who can remember many little details of what they have seen or experienced, there are also people who are comparatively slower in learning new skills or have difficulties to remember things.
People are different in terms of mental capacity, in other word intelligence, some are pretty smart, some are not that smart, and most are just as average. Intelligence quotient (IQ) is a score that aims to assess a person's mental capacity - the ability to acquire and apply knowledge and skills.
IQ test is a way, in which to ask a number of questions and based on answers provided by users, so as to calculate the user's intelligence quotient score.
For this IQ test, the median raw score of all users is defined as IQ 100, and scores each standard deviation up or down are defined as 15 IQ points greater or less. By this way, approximately 2/3 of the users' scores are between IQ 85 and IQ 115. About 2.5% of the users scores above 130, and 2.5% below 70.
As 'Intelligence' is such an abstract concept, no concrete measure of intelligence can be achieved, so IQ score is just an estimate of intelligence.
IQ scores have been shown to be associated with factors such as morbidity and mortality, parental social status, and biological parental IQ.
IQ scores are used for educational placement, assessment of intellectual disability, and evaluating job applicants. In research contexts, they have been studied as predictors of job performance and income. They are also used to study distributions of psychometric intelligence in populations and the correlations between it and other variables. Raw scores on IQ tests for many populations have been rising at an average rate that scales to three IQ points per decade since the early 20th century, a phenomenon called the Flynn effect.

Mental Abilities
According to Thurston, there are about 7 dimensions of one's mental ability as listed below.
- Verbal Comprehension
- Number Aptitude
- Spatial Visualization
- Perceptual Speed

- Memory
- Inductive Reasoning
Verbal Comprehension relates to the ability to understand the meaning of words, concepts and ideas.
Number Aptitude is the ability to quickly and accurately compute number related problems.
Spatial Visualization is the ability to visualize and manipulate patters and forms in space.
Perceptual Speed is the ability to grasp perceptual details quickly and accurately and to determine similarities and differences between stimuli.
Word Fluency relates to the ability to use words quickly and fluency in performing such tasks as rhyming, solving anagrams, and doing crossword puzzles.
Memory is the ability to recall information such as lists of words, mathematical formulas, and definitions.
Inductive Reasoning is the ability to derive general rules and principles from presented information.
