The method that was used to collect data is explained in detail like how did to generate random data of five sets with each set consisting of 500 products using Microsoft Excel ad procedure I followed to find the real-time delay time.As you increase the level of perspective in terms of abstraction, all humans may eventually come to look similar, even the same.

In methodology chapter, the researcher discusses about the framework elements of research such as knowledge claims, strategies of inquiry, and methods.They are used to address and improve poorly worded questions, and to help the investigator match the research goal to the method.It provides the importance of the study when compared to the prior studies and also benchmarks the results with other findings.Justification of the study - I gave a justification on for what I am working on this study and supporting what I say.This is not an example of the work written by our professional essay writers.

Quantitative vs. Qualitative Methods to Establish

By limiting the number of questions and limiting the ways in which participants can respond, the data can be gathered at a lower cost with often a higher level of statistical validity.Inter-rater reliability The degree to which each evaluator evaluates the same in similar contexts. involves the degree to which each evaluator evaluates the same in similar contexts.After knowing the type of approach, proceeded to various steps like experiments, data collection.I qualitative research, internal validity refers to the match between the researchers observations, interpretations, categories and reality.

Reliability and Validity - Research Methodology

One way you can address the value of validity is to cite all your sources clearly.I took care of the external validity by inferring the data to their respective parts, products and machines correctly and obtained results after performing a careful analysis.The discussion also includes the method of computation or derivation of the study.Where a qualitative research project may involve a dozen interviews, a quantitative one would involve hundreds or thousands.The approach that matches to my problem is quantitative approach.

Finally, explained the significance and outcomes of the study.He also investigated on how the new knowledge claims are constructed for the present-day research article introductions in economics and linguistics.The study involves development of a random data for careful observation of the delay time and analyzing the generated data in a real-time analysis for finding out the causes such as delay time and its effect o the productivity of the system.Credibility is nothing but the data, data collection and the results obtained are trustworthy and believable.My independent study is related to quantitative research model.

All or some of these reasons may be the foundation for writing the scholarly literature into a study (Miller, 1991).The risk and protective factors we learn from broad research projects involving thousands of subjects have value, but there are times when a broad brushstroke will fail to capture the fine data that is needed or desired.The experiments that I conducted for my study include visiting four manufacturing industries, observing the flow of products on different manufacturing production lines, and finally analyzing the type of model or an algorithm to be developed.Winter, G. (2000). A comparative discussion of the notion of validity in qualitative and quantitative research.RELIABILITY AND VALIDITY IN ETHNOGRAPHIC RESEARCH. variations in the ways problems of reliability and validity.Capturing fine data points and representing them in words and symbols can be a significant challenge for researchers. helps people like you help teachers fund their classroom projects, from art supplies to books to calculators.

Understanding Reliability and Validity in Qualitative

If quantitative research handles large audiences well, qualitative research allows for in-depth interpersonal interviews that produce rich and meaningful results.Sometimes, a simulation model can also be presented for easy understanding.Designing Quantitative Research Katie Rommel-Esham Education 504 Threats to Validity.

Correlations, Reliability and Validity, and. the instruments used in quantitative research to. reliability and content validity,.Chicago, IL: Rand McNally. indicate that validity is often the best available approximation of the truth or falseness of an inference, proposition, or conclusion.They want to know you are right and not making false statements.In other words, Joppe (2000) stated that validity is the one if the obtained results are truthful and believable.The study involves recognizing the possible causes of a factor (work order) and determining the effects (delay time) of a factor by a careful observation and finally minimizing the effect or improving the performance (Productivity) of a system.
