Research about Research methods and Literature review

Hi, I need academic writer for searching and solving some questions about the research methods and Literture review Describe the difference between the following (a) Quantitative and qualitative research methods (b) Case study and experiment (c) Internal and external validity (d) One tailed and two tailed hypothesis test (e) Parametric and non parametric test Identify the research question(s) from the problem statements given below: (a) Performance measurement and analysis is crucial for steering the organization to realize its strategic and operational goals. Relevant performance indicators and their relationships to goals and activities need to be determined and analyzed. Current organization modeling approaches do not reflect this in an adequate way. (b) Deep web or hidden web refers to the hidden part of the Web (usually residing in structured databases) that remains unavailable for standard Web crawlers. Obtaining content of the deep web is challenging and has been acknowledged as a significant gap in the coverage of search engines. (c) Non-relational databases (often termed as NoSQL) have recently emerged and have generated both interest and criticism. Interest because they address requirements that are very important in large-scale applications, criticism because of the comparison with well known relational achievements. One of the major problems often mentioned is the heterogeneity of the languages and of the interfaces they offer to developers and users. Different platforms and languages have been proposed, and applications developed for one system require significant effort to be migrated to another one. (d) Mixed methods research is an approach that combines quantitative and qualitative research methods in the same research inquiry. Such work can help develop rich insights into various phenomena of interest that cannot be fully understood using only a quantitative or a qualitative method. Notwithstanding the benefits and repeated calls for such work, there is a dearth of mixed methods research in information systems. (e) Because digital games are fun, engaging, and popular, organizations are attempting to integrate them within organizational activities as serious components, with the anticipation that they can improve employees’ motivation and performance. But in order to do so and to obtain the intended outcomes, it is necessary to first obtain an understanding of how different digital game designs impact players’ behaviors and emotional responses. Problem 3. For each of the problem statement described in Problem 2, propose an appropriate research approach to answer the question(s) you identified. (10 marks) Problem 4. Write a brief literature review on Data mining for the Medical Field. Your review should (a) Define what big Data mining and Medical Field are, (b) Describe how Medical data is processed in Data Mining Project environments (c) State of the art in Data mining for Medical Field (d) Challenges (e) Future directions Use the APA style for referencing. The review should be in your own words. Do not try to copy or rephrase sentences from the papers.
