As being revealed in the Table 3, the standard deviation of the test scores is between 14.58 and 15.54 across the three test batteries.

Bermingham et al. (2013) also use CogAT assessment tool to assess the ability of sample population to recall everyday numeric information such as prices. The authors use 100 sample population for the experiments and the participants are required to memorize 12 prices that vary from 1 to 6 digits. The authors recruit the participants from the "The University of Utah Alumni Online Newsletter, University of Utah OSHER Life Long Learning Institute and University of Utah Educational Psychology Subject Pool" (Bermingham et al. 2013 p2).

The participants are a mixture of part time students, full time students, retired persons and employed professionals. The participants consist of 33 male students and 77 female students, however, three participants decline to disclose their gender. The ages range are between 18 and 69, where the mean age is 27 years and SD (standard deviation )=10.6 years. All participants complete some college education. The descriptive statistics were used for the CogAT number series subtest. (Bermingham et al. 2013). The results reveals that age is not related to the numeric ability of participants.

How are particular ethical, reliability, and validity issues being addressed?

The case studies use different strategies to enhance the reliability, ethical and validity of the tests and issues addressed. First, all case studies carry out the data analysis to clean up the data. For example, Lohman (2006) carries out the data screening using the statistical technique such as Chi Square, Standard Deviation, kurtosis and Skewness. The strategy assists in summarizing the data in a manageable form. Typically, the Mean values assists in comparing the scores of the participants for the CogAT Verbal, Quantitative and Nonverbal reasoning. Despite the strategy employed by the authors in enhancing validity and reliability of the case studies, however, the authors does not state the strategy used to carry out the ethical consideration.

Bermingham et al. (2013) in their case carry out ethical procedures for the study. The authors ensure that the study strictly adheres to the ethical policies of the University of Utah. The study also adheres to the state, local and federal laws relating to human research. These laws require all researchers to protect the information collected from the participants and the information is not to be transferred to the third party without the permission of the participants. Thus, Bermingham et al. (2013) adhere to these ethical rules and university policies in their research . The authors also ensure that the "University of Utah's Institutional Review Board" (p 2) approves the study designs, protocols and recruitment techniques before they start the study. As part of reliability, the authors use a quiet laboratory setting the test to enhance privacy of the participants. In essence, the authors give the participants plenty of time to recall the practice before submitting the answers.


The research fields for all the case studies are both in psychology and education. In essence, all the case studies use the CogAT tool to carry out the tests. The CogAT is an assessment tool that psychologists use to test student or individual ability on verbal reasoning, quantitative reasoning and non-verbal reasoning. The CogAT is an assessment tool that psychologists use to test student or individual ability on verbal reasoning, quantitative reasoning and non-verbal reasoning. Bermingham et al. (2013) use the students of the University of Utah as part of the participants. Moreover, the authors use the university policies to enhance the ethical consideration for the research. Lohman et al. (2009) research is in the fields of psychology and education because the authors use the psychological assessment tool to investigate the difference in the cognitive ability between male and female students. Moreover, their study use students for the experiments and the outcome of the research can assist in enhancing a greater understanding of the cognitive abilities of male and female students, which may assist the school counselor when advising the students on career plan. Thus, this paper argues that the three case studies overlap the fields of psychology and education. Typically, the educational psychologists, and school counselors can use the same tool to advice students on their career plan.

In essence, all the case studies address the demographic, cultural and linguistic backgrounds because the studies select the sample population based on the diverse ethnic groups in the United States. The White represent the largest majority of ethnic group in the United States, thus, all the studies select the White as the largest number of participants.

However, there are still statistical problem identified in the case. For example, not all the case studies use the descriptive statistics to summary large volume of data collected. Moreover, not all the case studies use percentages value to differentiate the difference between the CogAT scores. The use of percentages will assist an easy interpretation of the results by the stakeholder such as policy makers.

Despite the discrepancies, the information reveals that CogAT is an effective tool to test the student's capability in verbal reasoning, non-verbal reasoning and quantitative reasoning. Nevertheless, the study recommends that there is a need to focus on the use of computer technology to carry out the CogAT assessment rather than the use of the traditional pencil and papers.
