Statistical Analysis And Quantitative Methods

The research design and methods of a study are constructed based on identifying the research problem, developing the theoretical framework, and reviewing the literature (Merriam, 2009). However, the heart of any research design, according to Maxwell (2013), is the research questions. The research questions help to focus the study and influence the choice of research design and methods for data collection. “More than any other aspect of your design, your research questions will have an influence on, and should be responsive to, every other part of your study” (Maxwell, 2013, p. 73).

Biostatistics also taught us how to recognize study designs and write a summary and critique. This is helpful because it identifies positive and negative aspects of the study and an opportunity for other people to replicate the study and improve it. For instance, on the 26th of June 2017, I submitted a summary and critique about hand-washing. This article was a replication of a previous study and an extension

According to Yilmaz (2013) there exist two significant approaches to research with respect to studying the social and individual world. According to Creswell (2014) three types of design quantitative, qualitative, and mixed methods should remain in consideration when choosing a research designs at the start of the process. The two methods exist a quantitative and

AP Statistics is a great start to further your education in a math-related field. As this class will look impressive on your transcript and there is a possibility of college credit if you score well enough on the AP exam with accords to your college choice standards. The course will provide an in-depth overview of exploring data, sampling and experimentation, anticipating patterns, and statistical inference. You will study statistics and apply it to intricate problems.

Researchers or research teams who elect a quantitative study are going to determine the relationship between an independent variable and a dependent variable within a population (Babbie, E.R., 2010). There are two types of quantitative study designs: descriptive and experimental. A descriptive design typically measures the subject once and establishes the association between the independent and dependent variables (Mujis, D, 2010). An experimental design measures the subject before and after a treatment and establishes causality between the variables (Brians, C.L. et al, 2011).

Statistics are used in many different ways in my workplace. The use of statistics is for the improvement of quality care and safety. Statistics are also used to measure employee compliance in regards to hand washing and proper use of policies and procedures. We also use charts and graphs to show infection rates, skin integrity, falls within the facility, budget concerns, and many more. These graphs help hospital personal improve care and safety to provide quality care to all patients. Graphs can also be used to measure patient and employee satisfaction.

Welcome to the first module! This power point reviews research methodology, concepts, and terms that you learned in your undergraduate Introduction to Research Methodology and Statistics. The presented material provides you with a foundation for learning more sophisticated concepts and statistical techniques.

This course definitely improved my knowledge and ability by helping me build a foundation of statistical methods and principles. I feel that I am now able to perform advanced quantitative studies of research in my current health profession as a Healthcare Sergeant in the Army. I am now able to implement the probability theory on which inferential statistics are based as well as being able to distinguish between a statistical sample and a population. Throughout the course I realized through evaluation of my work and feedback from Dr. Willson that my weak points were conducting parametric and nonparametric inferential statistical tests with the chi-square analyses. I could have performed better by researching outside of the required readings

A company with factories located in New York and Michigan produce yarn, using two different types of machines; JC980 and VH80. Each factory uses only one machine type. The sample size is at 1 391 factories.

Course Description: This course is designed to give students the basic skills to organize and summarize data, as well as an introduction to the fundamental principles and application of statistical inference. The course emphasizes an

In the modern age of health,education and public safety, society relies on rigorous research methods to find answers to complex issues dealing with social issues and general concerns. Ultimately, some short-term research methods may initially fail; however, continued extended research should surely result in success and benefit future generations. Depending on the topic of research; some research methods might be more appropriate than others. For example, clinical and laboratory experimental trials might receive better consummation if they use Quasi-experimental and Classical Experimental design rather than Cross Sectional Studies and Longitudinal Studies which focuses more on psychological experiments and behavior studies (Addison) (2015).

Dear Statistics Students, some advice in succeeding in class is students should attend class to understand the material better. The class is a four-credit class and we go through a lot of material and if you do not attended class it can cause you to miss the material. The power points are an outline so attending class helps to understand the slides and concepts better. I would not be on the phone during class incase of missing examples of concepts. Another key to success would be to practice and study the homework to become prepared for the quizzes. I would definitely work through the problems on the homework several times to understand how to do the math and to fix your past mistakes. When taking the quizzes and tests I would read the questions

I graded my peers in the discussion forum and I learnt a lot from their post. I studied the remaining pages of chapter 5 of our textbook (In Introduction to Statistical Thinking (With R, Without Calculus by Yakir) and attempted the self-quiz three times before I got all the answers right on my own.

The design of an observation study is accomplished in various ways depending on the objective of the study, the type of data collected and available resources for the study (Science, 2017). There are many types of observation

A study design is the procedure that guides a researcher on how to collect, analyze and interpret observations. It is a logical model that guides the investigator while he navigates through the various stages of the research. Study types can be classified severally depending on the research strategy employed. A study type can be non-interventional that is ‘observational’ where a researcher just observes and analyses researchable objects or situations without intervening. Non-interventional study designs can be exploratory, descriptive or comparative. A study can also be
