In an essay of 500 words, use the scenario presented in part 1a, above, to answer the following questions:

1. What statistical test was used in Nelson et al.,      (2010)?
2. Did the authors use the correct statistical test? In other words, what was their rationale for using this test (i.e., were the variables discrete or continuous and was the test appropriate for this      type of data?)
3. What was the research question? How did the statistical test address and answer the research question?
4. How did the authors interpret the results of this  study?

This assignment requires that at least two additional scholarly research sources related to this topiAnalysis of Researchc, and at least one in-text citation from each source be included.

What Statistical Test Was Used In Nelson?

Research methods are the techniques researchers use to structure a study and to gather and analyze information relevant to the research question. The two alternative paradigms correspond to different methods for developing evidence. A key methodologic distinction is between quantitative research , which is most closely allied with positivism, and qualitative research , which is associated with constructivist inquiry—although positivists sometimes undertake qualitative studies, and constructivist researchers sometimes collect quantitative information. This section provides an overview of the methods associated with the two paradigms.

The Scientific Method and Quantitative Research

The traditional, positivist scientific method refers to a set of orderly, disciplined procedures used to acquire information. Quantitative researchers use deductive reasoning to generate predictions that are tested in the real world. They typically move in a systematic fashion from the definition of a problem and the selection of concepts on which to focus to the solution of the problem. By systematic, we mean that the investigator progresses logically through a series of steps, according to a specified plan of action.

Quantitative researchers use various control strategies. Control involves imposing conditions on the research situation so that biases are minimized and precision and validity are maximized. Control mechanisms are discussed at length in this book.

Quantitative researchers gather empirical evidence —evidence that is rooted in objective reality and gathered through the senses. Empirical evidence, then, consists of observations gathered through sight, hearing, taste, touch, or smell. Observations of the presence or absence of skin inflammation, patients’ anxiety level, or infant birth weight are all examples of empirical observations. The requirement to use empirical evidence means that findings are grounded in reality rather than in researchers’ personal beliefs.
