Psychological testing data

create a test report based on provided information. There is not time to obtain and use actual tests in this 8-week format, so you will integrate provided information from a real client. In addition to the discussion board posts, you will complete these additional assignments:

This is a brief multiple-choice quiz, reviewing statistical concepts that you need to know to competently use psychological tests. It does not count toward your grade, but it is important to use it as a guide to determine what concepts you need to review. The Statistical Concepts Quiz Download The Statistical Concepts Quizis also located under Resources.

==========================================

The following 10 questions , I did uploaded it too ( same questions )

Quiz: Statistical Concepts

1) IQ scores tend to be fairly stable over time. This is because IQ tests have high:
a) Validity
b) Reliability
c) Measurement error
d) Cultural fairness

2) IQ scores correlate highly with academic performance. This is an example of IQ test:
a) Validity
b) Reliability
c) Discrimination
d) Parallelism

3) Knowing a test’s standard error of measurement tells us:
a) The likelihood of scoring errors
b) How test taker distractibility distorts responses
c) The likelihood that test takers will answer questions incorrectly
d) How many points test scores are likely to vary over time

4) Dr. Hathaway writes the following statement in a test report: “Jennifer’s Verbal Comprehension Index of 102 is slightly higher than her Perceptual Organization Index of 99. This difference reflects slightly stronger verbal than non-verbal skills.” This statement:
a) Accurately describes a significant VCI/POI difference
b) Is inaccurate because the score difference is non-significant
c) Is accurate because the non-significant VCI/POI difference is described as “slight.”
d) Is inaccurate because the VCI is above average, the POI is below average, and thus the difference is not “slight.”

5) Jose’s WRAT-IV Spelling score is significantly higher than his Word Reading score, at a 5% level of significance. This means that:
a) Only 5% of the population has a difference between these scores at least as large as Jose’s
b) There is a 95% chance that Jose’s Spelling score will still be higher than Word Reading if Jose is retested
c) There is a 5% chance that the Spelling/Word Reading difference is due to test error
d) Both b and c

6) Convert a WAIS-IV IQ (Mean = 100, s = 15) of 95 to a z-score:
a) -0.05
b) -0.33
c) -0.95
d) 6.33

7) A z-score of 0.5 is at what percentile?
a) 25th
b) 50th
c) 69th
d) 84th

8) Abdul obtains a score of 13 on the WAIS-IV Block Design test. If this is the only information that you have, your best estimate of his IQ would be:
a) 87
b) 113
c) 115
d) 130

9) Someone who obtains a T-score of 60 on the MMPI-II Depression scale is scoring higher than what percent of the population?
a) 60%
b) 70%
c) 80%
d) 84%

10) Factor analysis is:
a) A statistical method that shows how variables cluster, based on the correlations between them
b) A modern form of psychoanalysis
c) A way to determine if group means are significantly different
d) A way to draw causal inferences from correlations between variables

Sample Solution

The articles chosen for this research were very helpful and profound. The articles explained how dyslexia works and how it functions differently in all students. The first article used was named Learning Disabilities by Max Wiznitzer and Debora L. Scheffel. This article stated the different learning disabilities involving students. They are present from birth or early childhood, neurologically based, and impact on the ability to learn or process information. Later on in the article it stated how Dyslexia was 80% of the disabilities that children had today. At the end of the article it stated how you can find out if your child has Dyslexia. The physician is the first professional approached by the family with concerns regarding developmental functioning. The purpose of this visit should include problems that the physician may have seen in your child. After he or she should refer you academic testing or any methods of teaching to help your child. Neurologic Examination of the School-age and Adolescent Child was an article that pertained to helping to better understand how Dyslexia comes about. The neurologic examination is a very versatile diagnostic instrument when determining Dyslexia. When using it one should detect localizing and lateralizing signs of nervous system abnormalities, and determine reliably the maturational level of cognitive, emotional, and motor capacities, as well as physical growth and development. Standardized test are usually helpful to analyze age appropriate specific hearing and visual loss problems found on the neurologic evaluation; to evaluate nerve and muscle functions further; or to quantitatively characterize developmental language disorders or dyslexia. Results were found an article called Quality of phonological representations, verbal learning, and phoneme awareness in dyslexic and normal readers, the article stated that results pre-test measures are displayed in two different groups. The two groups differed significantly on the measure of non-word decoding even though they matched closely on silent word decoding. In high school it gets even harder for students who have Dyslexia. Most of them become shy and even withdrawn from others while trying to finish their career in high school; sometimes even end up being put in special education. The article named Visual skills of poor readers in high school shows how some students in California were suffering in high school from being Dyslexic. Visual skills and visual acuity were measured in 461 students (average age 15.4 years) in 4 California high schools within the same school district. Participating st
