Cons • One problem with observation is that it can be very resource intensive. It might involve great amounts of time and energy, which can be a problem if those resources are not available in adequate quantity. If there is less time for the research to be carried out it might lead to hurried observation which dilutes the quality of the data collection process and thus has an adverse impact on the analysis • Since observation is being carried out by a human being, there exists a risk of observer bias. It is not necessary that the observer will always be unbiased and thus there will always be a question mark over the sanctity of the data collected. •
Indeed, the method is expensive and time consuming. And the method is also inflexible since after the study begins, the instruments cannot be modified (Bamberger, 2000; Rao and Woolcock, 2003; Sumner and Tribe
Task 4 In-club to produce an empirical and highly practical research , the research worker must use a combination of quantitative and qualitative approaches; the researcher must consider which of the diverse methods used in research are most appropriate for the probe and answering of the head . The option of methods and the way in which they are implemented will largely be determined by the research question , but will also be influenced by practical consideration, such as material handiness . Research may involve either empirical data (“fact” identified within a pre specified conceptual view) or conceptual data. Empirical inquiry is often adding up answer to describe situation or to test theory .
Mr. Jillson is not a contractor and therefore cannot testify regarding damages under Minn. R. Evid. 702. For the foregoing reasons, the Court must exclude any and all testimony from Mr.
It is difficult to analyze such information effectively, as it requires a lot of time and analysts. This means that finding valuable information using this approach might be difficult or even impossible. The use of encryption and other secure forms of communication can restrict access to data. A change in the communications protocol, for instance, adopting another mode of communication can also lead to loss of access.
Many people claim to be adept in multitasking, but in reality they are less efficient than those who isolate one act until its completion. Rather than smoothly and equally completing parallel task, the brain instead has to yank its focus from one task to the other, causing a lag in productivity. Although individuals do not notice this lapse, studies have shown the shift between task causes multitasking to take 40% more time than just single tasking (Plessow, 2). This inferior form of completing work is called serial tasking, and according to The National Academy of Science people who consider themselves great multitaskers actually are cognitively worse off than non multitaskers (Taylor, 1). For example, they remember less and take longer complete
It also lays the foundation for higher logics FOL (First Order Logic) for e.g... It also provides Reasoning methods which are decidable. The Disadvantages being that it is not expressive enough to solve most problems and hence a need for alternate method still exists. Also even if it happens to be expressive in some case it becomes very un-concise.
The administration of a structured questionnaire creates an unnatural situation that may alienate respondents. Studies are expensive and time-consuming, and even the preliminary results are usually not available for a long period of time. Research methods are inflexible because the instruments cannot be modified once the study begins. Reduction of data to numbers results in lost information. The correlations produced (e.g., between costs and benefits, gender, and access to services or benefits) may mask or ignore underlying causes or realities.
Disadvantages of Qualitative method The primary disadvantages related with qualitative methods are at first, the procedure is tedious, and besides, a particular, vital issue could be overlooked. The second potential issue is that a particular issue could go unnoticed. All researchers‟ translations are constrained. As situated subjects, individual experience and information impact the perceptions and conclusions.
This means that having access to fair opinions is not always possible. The group may bring many greater alternatives, that may higher quality than individual. Then it is likely that the group will reach a superior problem solution than the individual finally. Group members can identify more perfect and possible solutions and recommendations through discussion.
