in some cases confused with subgroup analysis is the sensitivity analyses for the study. Although some sensitivity analyses include restricting the analysis to a subset of the studie. There is two methods differ in two ways. He first way is sensitivity analyses do not attempt to estimate effect of intervention in the group of studies removed from analysis and the estimates are produced for each subgroup. The second way is sensitivity analyses informal comparisons done between the ways of estimating the same thing, in subgroup analyses formal statistical comparison are made across the
The case study method is the preferred choice of methodology given that it allows the researcher to explore additional avenues of information that may arise in the case study of the participating higher education institution (HEI). This study used a descriptive case study methodology. A descriptive case study was most fitting for an analysis that was dedicated to answering “how” and “why” questions about a given phenomenon (Yin, 2009). The purpose of the current study was to learn how and why internationalization has developed at the different HEIs. Case studies allow for selective sampling strategies, employ multiple methods of data collection, and provide a richer understanding of the topic which will focus on the particulars and the complexity, the uniqueness and
Under inferential statistics, reliability analysis and a logistic regression has been done. Descriptive statistics are used to represent analyzed data in a meaningful and a clear way. 4.2 Reliability Test. Reliability analysis for this research allowed studying the properties of measurements and scales and the items that compose scales. Reliability analysis calculates number of commonly
There are at least three situations that create a desire to employ a case study method of research. The first reason to employ a case study method of research is determined by the question itself that the study is trying to address. Case studies are relevant when one is attempting to addresses either a descriptive question “what is happening or what has happened?” and an explanatory question such as how or why did something happen the way it happened. Secondly, by give emphasis to the study of a phenomenon within its real-world context, the case study method of research favors the collection of data in natural settings, compared with relying on already derived data. Thirdly, case studies as methods of research are now commonly used in conducting
This relates to its concern with tracing the causal pathways of specific deprivations, with how exactly different people are able or unable to convert resources into valuable functionings. Sen’s Capability Approach is founded on the idea that much more information about the quality of human lives can and should be taken into account in evaluating
For example, a flowchart of routine checkup process by a patient in some hospital can be seen in figure 3.3.3 Figure 3.3.3 Flow Chart of patient activities in a hospital 3.3.4 Scatter Plots The Scatter plot is another problem analysis tool. Scatter plots are also called correlation charts. A Scatter plot is used to uncover possible cause-and-effect relationships. It is constructed by plotting two variables against one another on a pair of axes. A Scatter plot cannot prove that one variable causes another, but it does show how a pair of variables is related and the strength of that relationship.
Taylor and Sparkes (1977) discuss the importance of sensitivity analysis in strategic evaluation. Sensitivity analysis considers how sensitive a project is to changes in the assumptions that underlie profitability forecasts. Important factors to consider may include how the following affect profitability: changes in sales, prices, interest rates, costs and in exchange rates. Lynch (2003) suggests that sensitivity analysis gets to examine all the assumptions behind any strategic option, and how any change would influence the suitability, feasibility, and acceptability of the
Next we consider the limitations, strengths, and weaknesses of project selection models, including some suggestions of factors to consider when making a decision about which, if any, of the project selection models to use. We then discuss the problem of selecting projects when high levels of uncertainty about outcomes, costs, schedules, or technology are present, as well as some ways of managing the risks associated with the uncertainties (Jack R. Meredith, Samuel J. Mantel, Jr: 8th Ed:
First, using previous research as well as the instinct of the researcher, one use theory to predict relationships among or differences between selected variables. This variables selection process and the theoretical explanation of how they are related is referred to as isolating a particular research problem where the researcher then identify appropriate hypotheses to be tested completes the isolation process. Second, research design selection follows once the appropriate variables relevant to the applicable theory had been identified. As mentioned above, there are two general design options: experimental designs and survey designs in quantitative communication research. Experimental designs are typically best suited for making causal claims and describing differences between groups while survey designs are best suited for describing characteristics of groups and explaining relationships between variables (i.e., correlations).
Obviously this method requires that members of the organisation are used to measure different characteristics. However, in some organisations, there are no such things as gauges, and if they exist, they are often inadequately calibrated. Another barrier when conducting process capability studies is the high speed of modern production. In some operations there is simply no time left to perform measurements, which enhance the importance of capable processes. Another aspect of this problem is that important characteristics are sometimes hard to measure and control.
