¶ … attainment of a desired research goal is to develop a scientific approach toward the situation, event, occurrence, or phenomenon being investigated. As such no research question can be answered by way of gathering and analyzing data if first investigative issue is not stated in testable terms or form. Once a research investigator has established and properly formatted the specific research design to be used to investigate and test a desired phenomenon attention can be given to the required method of data collection. On the basis of the method chosen the researcher will be permitted to draw the necessary conclusions from the data statistically analyzed. Should a research investigator not choose the best-fit method of data collection then any inferences drawn from the data analysis are subject to a tremendous amount of error and inaccuracy. In order to avoid data error and inaccuracy the research investigator must give particular attention to how the data to be analyzed is collected or what is better known as sampling procedure. Sampling alone can skew testing results, infuse uncontrollable error into statistical processes, and violate the empirical premise under which to research investigation is being conducted (Ohlson, 1998). In order for accurate conclusions to be drawn about any research endeavor there must exist an adequate sample size as well as employing an appropriate sampling structure. The best-fit sampling methodology to use in a research investigation is that of random sampling. Random sampling is the method of drawing a portion or sample of a greater population so that each member of the population has an equal chance of being selected to participate in the research study. Without true randomization of the sample, measurement data, and the conclusions drawn thereof, are weakened, contaminated with error, and generally suspect. Should the data sampling methodology not be based on random selection representation to a greater population is subject to misrepresentation. Further,...
Other important considerations with respect to data collection is in knowing that errors of measurement are greatly reduced as sample size increases and the sample size must be large enough to reduce potential measurement error. The slightest movement in measurement error can oftentimes cause a change in the mathematical quotient of the required statistical value; thus producing results that may of may not be sufficient to accept or reject the testable null hypothesis.
Bio-Statistics Research activities, whether clinical trial based, experimentally designed, or product oriented, must exhibit and command interest, enthusiasm, and passionate commitment. To this end the researcher must catch the essential quality of the excitement of discovery that comes from research well done. The first step in the attainment of the desired research goal is to develop a scientific approach toward that which is being investigated. A requirement within the scientific
The Challenges of Dual Credit: A Research Proposal Problem Statements Dual credit or dual enrollment programs “are designed to boost college access and degree attainment, especially for students typically underrepresented in higher education,” (United States Department of Education, 2017, p. 1). With this lofty goal set, it should seem that dual credit programs would be reducing the educational achievement gap. After all, dual credit programs by definition allow all students the opportunity
Goal Setting Theory Application The goal setting theory was a product of the research conducted by Edwin Locke and Gary Latham who carried out more than 400 separate studies in this regard. They indicated that goals have a pervasive effect on the behavior of the people working within a given organization hence there is need for care and attention while setting goals since with the right conditions, goals can be powerful
Good researchers tend to pull methods out of a tool kit as they are needed" (2006, p. 54). Notwithstanding these criticisms and constraints, though, most social researchers seem to agree that classification by some type of research paradigm is a useful approach based on the need to determine which approach is best suited for a given research enterprise. In this regard, Corby concludes that, "The contested nature of research
Statistics and Their Importance to Research Investigation. Although all research activities do not require the use of statistical data analysis when an investigator wants to report upon the differences, effects and/or relationships between and amongst groups or phenomena (i.e. variables) there must a concerted effort to measure the phenomenon with as much precision and accuracy as possible (Mendenhall & Ramey, 1973). This is, of course, accomplished through the use of
