The primary reason for considering this is to indicate how the research will be accepted as a piece of academic writing. Reliability and validity are two criterions that are used to judge the functions of research designs and measurements. This paper will also look into why it is important to ensure that data collection methods as well as the instruments are reliable and valid. In addition, the current management within the department might be altered through transfers hence; this might slow down the research process completely. To answer the research questions, data was collected from financial statements of agribusiness case from Egypt and the survey was conducted. Step 5: Define the Population Research projects can focus on a specific group of people, facilities, park development, employee evaluations, programs, financial status, marketing efforts, or the integration of technology into the operations.
According to Stenbacka 2001 , within a qualitative framework reliability is concerned with generating understanding in contrast to a quantitative research that reliability is concerned with purpose of explaining. Research demonstrates that information sharing is facilitated by familiarity, and having a common understanding of problems, use of lexicon, and semantic meaning. The instrumentation plan serves as the road map for the entire study, specifying who will participate in the study; how, when, and where data will be collected; and the content of the program. Six types of reliability are considered: test-retest, interrater reliability, candidate consistency, interviewer-candidate interaction, internal consistency, interrater agreement. A sample size of about 30 staff will then be chosen.
This correlate with the theoretical perspective of interpretivism. Reliability is the prerequisite for validity. Human Resources and Personnel Management. For example if the applicants are given different selection tests it would be very difficult to compare the difference among applicants. The researcher finally has data to analyze so that the research question can be answered.
Reliability is an important criterion in regards to research and refers to the degree of consistency or stability of a measure. Without them research and their results would be useless. Ensuring that interview is valid or not needs validation studies. . The indexes and abstracts may be in print or computer-based formats or both.
Studies In Interpretation Of The English. Cyber forensics: a field manual for collecting, examining, and preserving evidence of computer crimes, 2nd Ed. These professionals need to understand the eight steps of the research process as they apply to conducting a study. Reliability and validity are key concepts in the process of selecting among job applicants, since the main goal of selection is to make accurate predictions about which individuals will perform well on the job. Journal of Documentation 34, 55-85. In this process, the study is documented in such a way that another individual can conduct the same study again. This said, researchers attempt to follow the process and use it to present their research findings in research reports and journal articles.
Watch for book-length bibliographies and annual reviews on your subject; they list citations to hundreds of books and articles in one subject area. Conversely, adopting behaviours that promote common frames for understanding interteam capabilities and information requirements improves information sharing and potentially reduces cognitive effort required to process information. Morris and Wood 1991 states that the case study strategy is of a greater interest if the researcher wishes to gain a rich understanding of the context of the research and the process being enacted. Hence, this expanded and restructured edition of John Creswell's Research Design is a user-friendly and rich scientific resource, and appears as a must for any researcher wanting to tackle the indispensable subject of research design by contrasting qualitative, quantitative, and mixed methods approaches. Caswell, F 1985 Success in statistics, London. On an unreliable examination, a student's grade or score may be. Remeyi et al 2005:104 nicely summarised the underpinning features of objectivism and constructivism in the table below:- Objectivism Constructivism Basic beliefs: World is externally and objectiveObserver is independent World is socially constructed and subjectiveObserver is part of what is been observed Focus on meaning Researchers should: Focus on factsLook for causality and fundamental lawsReduce phenomena to simplest elements Formulate and test hypothesis Try to understand what is happening Look at totality of each situation Preferred methods: Operationalise concepts so they can be measuredTake large samples Use multiple methods to establish different views of phenomena Small samples investigated in depth or over time Source:Remeyi et al 2005:104 Research Approach: Inductive and Deductive Research There are two major approaches to a research development namely induction and deduction.
The research process involves six distinct phases, although they are not always completely linear, since research is iterative earlier phases influence later ones, while later ones can influence the earlier phases. Alternatively, if a number of candidates are given the same selection test, the test should provide consistent results concerning individual difference between candidates. Alternate-form reliability refers to the degree of relatedness of different forms of the same test. Being concept to measure the predictive validity and reliability of future job performances, it is the most important property when assessing an employee for selection Schmidt and Hunter, 1988. The researcher will use focus group discussions as third method to gather data. South African journal of Library and Information science.
After discussing the nature of validity in qualitative research, the author details the philosophical and practical dimensions of: descriptive validity, interpretive validity, theoretical validity, generalizability, and evaluative validity. First, we offer a tripartite argument for how experiential learning is inhibited. Experiential learning is essential for many high-performing teams, yet there are also challenges to its incorporation into team training. Problems deriving from poor hires are largely high cost of rehiring and retraining, friction amongst staffs as well as resentment of other better workers. A more reliable instrument is often called as stable instrument that instrument which gives same or very closer results where as less reliable instrument is often called unstable instrument that gives different results on every trial. The measurement of reliability almost always involve some irregularity due to constraints such as the difficulty to simulate the same conditions and parameters for an assessment.
Collis and Hussey2003 Deductive approach in a research works from a more general to more specific and conclusions can be drawn from an available theory. Since we maintain our humanity throughout the research process, it is largely impossible to escape the subjective experience, even for the most experienced of researchers. To be read in conjunction with an article originally published in Curriculum Support, Science, 2001 Vol. Reliability and Validity are important aspects of research in the human services field. Citing or documenting the sources used in your research serves two purposes, it gives proper credit to the authors of the materials used, and it allows those who are reading your work to duplicate your research and locate the sources that you have listed as references. All of these areas cannot be investigated in a single study; therefore, the problem and purpose of the study must be more clearly defined.
