Because this scale is based on perception, there will always be some sort of discrepancy but it has proven to be a reliably source and measure for the adaptive behavior.

The test under analysis is the Stanford-Binet Intelligence Scales, Fifth Edition (SB5) which is thoroughly explained through the technical manual of the intelligence assessment (Roid, 2003). The Stanford-Binet Intelligence Scales, Fifth Edition, Technical Manual and the SB5 test in general was authored by Gale H. Roid (Roid, 2003). The manual was published by Riverside Publishing in the year 2003 after enduring many years of development (Roid, 2003). The SB5 is an assessment of both cognitive abilities and intelligence (Roid, 2003). The SB5 complete kit is provided via the publisher for the total price of $1...
According to the website, I have an IQ of 113. I feel as though a site like www.iqtest.com could produce a “g” score because they make you pay too see an analysis of your results, which indicates to me that they put some effort into producing fairly accurate scores. General intelligence, also known as “g”, describes an individual’s specific mental ability, which is measured by tasks on an IQ test (Myers p. 405). The site breaks down your overall IQ results into different categories of intelligence and gives you an IQ score for how well you tested in a given area. For example, there is a category for “spatial intelligence” which is ones ability to predict what actions will happen based on varied conditions (Website). By looking at the broken down results you can compare areas you have strengths in, versus the areas you might struggle in. This is in accordance to what Charles Sherman found when he discovered that people who score high in one area tend to score high in similar categories (Myers p. 405). For a person to see what their “g” score would be they would simply have to look at which category they scored highest in and from that they would see in which area they have the highest intelligence in.

Intelligence or IQ has been studied extensively. It has been found that in childhood the correlation of IQ between twins is about .5. This correlation has also been found to increase with age. Similar results have been found in adoption studies indicating that environmental differences are not as much of a factor on IQ scores.

Reliability of a test measure the stability of the test’s scores over a period of time or internal consistency of the test’s items. (Psychtech International). According to Tyler (2003), the Fifteen Questionnaire Plus have been used on various samples and it has confirmed good levels of internal consistency when the length of the scales are taken into account. Tyler (2003) further states that Psytech South Africa made evidence available on their website of internal consistency reliability. It is assumed that the 15FQ+ is a reliable measure of personality in South Africa, even though the alpha levels are usually lower than in UK samples, however, in comparison to those obtained in South Africa it is favourable from other measures of personality. Psytech South Africa is conscious that literacy and education levels is a challenge and does put constraints on the test’s use and interpretation, therefore, it does not endorse using the 15FQ+ for broad entry level screening outside the United Kingdom.
