An association between rates of COPD exacerbations and the use of cholinesterase inhibitors was researched in a report entitled “COPD Exacerbation and Cholinesterase Therapy in Dementia Patients.” Thus, the rate of exacerbations in…

Internal validity There is a causal relationship between the independent and dependent variable (Kelley, T,L.; 1927). Internal validity is shown in the personality test by using standardised instructions and counter balancing by two options being provided while the respondent has to choose one option in every question. Face validity According to Nevo, B (1985), face validity can be described as whether the test appears (at face value) to…

Furthermore, the efficiency of self-reports is the highest when used for a large group of participants, and are usually high in face validity, meaning that each construct assessed is clear to both participants and researchers involved (Cyders & Coskunpinar, 2011). However, it is important to note that there a few significant weaknesses of self-reports as well, with high face validity translating into inaccurate answers, a limited range of underlying cognitive processes that can analysed, being…

published, the statistical methods that have been used are correct. “Unscrupulous medical research not only halts the progress of medical knowledge, but also creates unanticipated consequences. For example, this has vividly occurred in the case of concurrent data and the association between autism and immunization. Research misconduct chastises the reputation of research groups and institutions in the scientific…
