Can you please offer a good way to remember how to differentiate between these varying tests? Mnemonic, association, or whatever you can conjure up so that it will be easy to discuss during mid-term essay (memory only).© BrainMass Inc. brainmass.com October 25, 2018, 9:29 am ad1c9bdddf
The Standard-Binet (SBS) measures five Cattel-Horn-Cattell (CHC) factors names, and the cognitive ability being measured; and verbal and non-verbal factors. The Wechsler Intelligence for children is a revision of the WISC-III. It was updated to improve test items as well as norms. According to Cohen and Swerdlik (2005), what is most noticeable about the WISC-IV, similar to the SBS, the test adheres to the CHC model of intelligence—that is a measure of a general factor of intelligence. Both tests have child-friendly materials; and both have available software for scoring and report writing. While there are noticeable similarities with the two tests; there are differences as noted by Cohen and Swerdlik.
For example, the SBS can be used with test takers who are much younger and much older than test takers who can be tested with the WISC-IV. Although both are administered with the use of 10 subtests, the WISC-IV contain five supplemental tests; while the SBS does not contain any. The SBS can be modified to develop a short form that can be obtained as an Abbreviated Battery IQ with the administration of two subtests. The WISC-IV does not include short forms, nor can one be constructed. The WISC-IV include parent education as a variable that the SBS does not include. The SBS5 includes socioeconomic status, and test taker education that the WISV-IV do not include. In addition, there are differences to remember in the manner in which subtests are indexed (Cohen & Swerdlik, 2005, p. 281).

Is data sufficient to test better memory scores with new herbal supplement?
A researcher is testing the effectiveness of a new herbal supplement that claims to improve memory performance. A sample of n = 25 college students is obtained and each student takes the supplement daily for six week. At the end of the 6-week period, each student is given a standardized memory test, and the average score for the sample is M = 39. For the general population of college students, the distribution of test scores is normal with a mean of µ = 35 and a standard deviation of σ = 15. Do students taking the supplement have significantly better memory scores? Use a one-tailed test with α = .05.
These data ________(are OR are not ) sufficient to conclude that the supplement has a significant effect.View Full Posting Details
