Wechsler IQ tests - Reasons of Popularity
The Wechsler IQ tests have been getting more and more popular with the passing of time. Every new version tries to remove weaknesses of the previous one. Even the first Wechsler Intelligence Test, in 1939, was a major development in the testing industry.
It is not for the reason that they have developed the perfect system to measure your intelligence...
...but for the reasons:
1- Easier to administer
2- Easier to compute
3- Easier to compare, and
4- Easier to revise whenever required.
Easier to Administer
David Wechsler and his followers have developed more than 10 different major Wechsler I.Q Tests so far. They all remained loyal to the basic content and format. You can find very little variation in the number of sub-tests. At least eight sub-tests are present in the whole family of Wais intelligence tests. The examiners find it easier to switch from one Wechsler IQ test to another for administering purposes.
Easier to Compute
It is not only easier but also better to compute your mental functionality in different sector. A single global IQ score is no more acceptable. Wechsler tests provide the system to measure your specific strengths and weaknesses. Each section helps in collecting very useful data for your personality profile.
Furthermore, the mean for IQ and Index scores is standardized at 100. The standard deviation is 3 and 15 for sub-tests and the overall calculation of your scores, respectively. This helps the examiners to analyze your capabilities in different sections.
Easier to Compare
The Wechsler tests have made it possible to compare functionalities of your right and left hemispheres of your brain, separately. There are 5-6 sub-tests in the verbal scale and 6 in the performance scale. A joint description of these two factors of intelligence may explain your collective smartness.
Easier to Revise
The Wais tests have gone through many revisions so far. It is merely for the fact that David Wechsler had established a formula to switch from one version to another, easily. Many generations have been produced and many more are in offing.
