Critical appraisal entails balanced assessment of the strengths and benefits of research against the weaknesses and flaws and aims at ensuring high quality maintenance in research (Gerrish & Lacey, 2006). The factors that must be assessed when critically appraising quantitative…
are true for the people in the study while external validity is the reflection to the target population by the study for people who are not included in the study. Biases that may lead to internal invalidity include statistical analysis, withdrawals and dropouts, blinding, data collection methods, allocation bias, confounding, intervention integrity. Internal validity occurs in unbiased results and only internally viable research can be generalized ensuring external validity.
Reliability denotes the amount of trust that can be given to a research and is therefore a measure of the likelihood for reproducing the same research (LoBiondo-Wood & Haber, 2010). This is determined using statistical techniques relating to frequency of occurrence of chance and uncertainty of an observation. The threshold for chance use to check for reliability is 5% where a research phenomenon is reliable if it occurred more than 5% and its occurrence is therefore not by chance.
Applicability is the extent to which the results obtained can have an impact on practice where contrast is made against statistical significance. This entails checking if the research will generate any difference on the users of the research.
The most important factor is validity because applicability is dependent on reliability and validity but results can be reliable but not valid making them unable to be generally applied. It is also more important because reliability is a necessary condition for validity however it is not a sufficient condition. In conclusion, it is more important where the research outcome is both reliable and valid for the best research ...

Quantitative researches typically specify the number of research participants as sample from the population and display the data on numerous events taking place or biological variables. There is a statistical section in the research that reflects the cause and effect relationships.
Such factors are of major interest to schools of nursing and members of their faculty as they may be able to adjust their curriculum or admission requirements accordingly in order to achieve a higher rate of passing in the examination. Findings of this investigation may also help future test-takers in determining the type of preparatory programs and courses that they should take in order to aid them in succeeding at the examination.
As Bonner, Wiggin, and Incontrera (2009) point out, through quantitative easing, a central bank generally purchases different types of financial assets to pump a fixed volume of money into the economy with intent to promote economic activities and thereby to boost growth rate (p.
Beyond its adverse effects on patients’ mortality rates, this infection places enormous costs of healthcare system by increasing the length of time patients must stay in Intensive Care Units. In response to this problem, IHI (2004) created a protocol called the VAP Bundle, which consists of five evidence-based practice interventions, applicable in daily practice for mechanically ventilated patient results in a dramatic reduction in incidence of VAP.
Generally, it is desired that this will have a 95% confidence level with a margin error of 5% as stated by GEO (2006, p.1). Qualitative research reflects data compiled by personal observations of people and what they say and do, and in the case of diagnosed schizophrenia, what stigmas are attached, as indicated by Knight et al.
Quantitative research confounds exist that influences research results against independent variables’ forces and therefore challenges implementation of quantitative research. History confound, maturation confound, and testing confound are examples of challenges to quantitative research.
Harvey (2002) describes quantitative data as data which can be sorted, classified, measured in a strictly "objective" way - they are capable of being accurately described by a set of rules or formulae or strict procedures which then make their definition (if not always their interpretation) unambiguous and independent of individual judgments.
