The Reliability and Validity of Hans Eysenck's EPI Test
The aim of this investigation was to look at the reliability and
validity of Hans Eysenck's EPI Test. The EPI questionnaire comprises
of items of a 'yes/no' variety. They are essentially intended as
research tools (as opposed to diagnostic tools for use in clinical
settings) and, as such, 'they are regarded as acceptable, reliable and
valid' (Kline 1981, Shackleton and Fletcher, 1984).The Alternative
Hypothesis was that there would be a positive correlation between the
E and N scores for forms A and B of the EPI. The Null Hypothesis was
that there would not be a positive correlation between the scores for
forms A and B, and any such found relationship would be down to chance
factors operating.
The correlation study was carried out because we were looking for a
relationship between the E scores and the N scores for forms A and B
of Hans Eysenck's EPI Test. The independent variable and dependent
variable were not operationalised in this case because an experimental
method was not being used and this investigation used test re-test
reliability. A repeated measure design was used because it was quick,
economical and cancelled out individual differences. Eighteen naïve
psychology students, male and female were used for this investigation.
An opportunitive sample was used because it was quick, easy and could
be carried out in a classroom.
The results, taken from the Raw Score Data table and scatter graph
showed evidence of a positive correlation. However, to accept that
this result was significant, we subjected the data to further
statistical analysis. A Spearman Rho Correlation Coefficient test (Rs)
was chosen because the data was Ordinal and parametric assumptions
were not met. The outcome stated that with number of people equalling
18 and significance set at p=0.05 for a one tailed test, the
calculated value for the 'E' score was 0.87 and for the 'N' score was
0.90. The critical table value tells us that a value 0.464 and above
has a degree of accuracy to 0.
In the book The Examination by Malcolm Bosse two brothers travel across China in their journey to pass the Imperial Exam. The brother’s names are Chen and Hong. Chen is very intelligent and is taking the Civil Service Exams hoping to pass. Hong on the other hand, is a known cricket fighter and joins the White Lotus Society along with the army. The Examination takes place in Song Era and is very accurate about what Chinese life and society was like in that time. This book depicts ideas and technologies and religious structure of ancient China. In the book The Examination by Malcolm Bosse, the author depicts ideas and technologies such as the civil service exam, junk ships, and porcelain as well as the religious structure of
Standard scores are a more appropriate way to report scores because they are standardized. They have a range at which an individual’s score could fall. There are many limitations the use of AE scores has and SLP’s should not continue to use them in reporting results of norm-referenced
First of all, this case is associated with biopsychosocial approach which recognizes that, it is the approach that considers human behavior to be the result of interactions of integrated biological, psychological, and social systems. This approach helps us to recognize the ways in which women’s biology, psychology, and their social world intertwine within each other affect their reactions to alcohol and alcohol interventions. In order to explain some of the concepts and theories, we must first sort through the facts that have been presented in the case study. This particular case is concerned with developing a better understanding of the relationship between Casey, and alcoholism.

The MACI consists of a 160-item inventory, provided in the English and Spanish language, with a combination of the 27 subscales. The intention of the inventory is to provide counselors and other healthcare or school professional with information to assist in diagnosis and treatment planning for personality disorders in adolescent (Millon & Davis, 1993). The inventory consists of true or false questions; given that this inventory is shorter compared to other personality assessment, it only takes about 20-30 minutes to complete. Millon’s MACI inventory provides convenient and cost-effective methods for scoring the inventory, which include Q-global web-based scoring, Q-Local software-based scoring, and mail-in scoring. Since the MACI is tailored toward adolescents ranging in ages from 13-19, participants must have a minimum of a sixth grade reading level in order to
There are two basic psychometric properties, validity and reliability that have been used to evaluate the quality of scale development. Psychometric testing used to evaluate the quality of instrument (Polit& Beck, 2010).

After completing the Clifton strength finders test, I learned my dominant strengths and it gave me a sense on what areas I am strong in. It allows you to work in the areas that you are good in and not in the ones you might not be as strong in. My top five strengths were learner, connectedness, belief, positivity, and includer. A lot of these I figured I would have because I am an athlete and I love to be positive. That is good because I practice these strengths every day which in turn will make me better at them and will allow me to use them in my career.

As stated earlier, this concept of measurement is mainly used by psychologists in making decisions when the difference between two test scores is significant and when the difference is inconsequential. Therefore, during MBTI testing, it is important to come up with a standard error of measurement which will help in determining whether a certain value represents a substantial difference between two people having different personalities. Through standardization, it will be possible to draw a concise difference between two personalities which are close to one another. It is through this that we are able to have a common way of determining the personality of a person
It can be said that there are numerous tests that have been created by psychologists all over the world, but of all those tests how many are as unique as the Millon? Through rigorous research and reading I have selected the Millon Clinical Multiaxial Inventory-III test. The Millon Clinical Multiaxical Inventory (3rded: MCMI-III) is a widely used psychological assessment of clinical and personality disorders (Grove, W. M., 2009). This test, now on its 3rd edition, has embodied several innovative ideas in personality and psychopathology assessment (Grove, 2003). Moving in-between the 3rd and 4th editions was a once in a lifetime opportunity and amazing learning experience. Through analysis of the MCMI-III manual and other sources this test can be explained and examined in depth helping to better understand this influential psychological assessment tool.
The aim of the experiment was to support the assumption that the participant who had a higher (overweig...
Limitations of the EDE-Q primarily centre on the lack of research for its use in males and adolescents, in comparison to norms available for young adult females. However these limitations are being addressed in more recent research, which is providing normative data in a broader range of clinical and nonclinical populations (Mond et al., 2006; Lavendar et al, 2010).
In today’s highly competitive job market it is extremely challenging and important for businesses to fill a vacancy with the right candidate (Cann, 2013). Due to high demand of potential candidates, developing a portfolio of employability skills which include psychometric testing is considered important in every workplace (Mills et al., 2011). Thus, I recently took three practice psychometric tests on verbal, numerical and inductive/logical reasoning. This essay is a reflection of my personal experience of psychometric testing. First, I will talk about what the literature comments on in relation to the strengths and weaknesses of psychometric testing. Then, I will assess whether literature reflects
