Types of Variables SLP 4
Module 4 - SLP TYPES OF VARIABLES Once a research hypothesis is formulated, the researcher must decide upon an appropriate study design to test that hypothesis. In doing so, she must take into consideration the extent to which that design will optimize the internal validity of her study findings (refer again the discussion of internal validity in Module 2). Also to be considered are the practical factors that may facilitate or inhibit implementation of particular study designs, e.g., limited access to one’s target population over time due to transiency among prospective research subjects may preclude adoption of a cohort study design. Your Task for this Assignment With the aforementioned factors in mind, identify a study design (experimental or observational) that would be appropriate to test your study’s research hypothesis, and address the following questions in a three-page essay: What are the components of this design? Would this design be considered experimental or observational? Why? Why did you choose this design over others? Be sure to note all advantages and disadvantages of employing this design to address your particular research question. To what types of bias is this design most vulnerable? Please explain. SLP Assignment Expectations You are expected to consult the scholarly literature in preparing your paper; you are also expected to incorporate relevant background readings. Your paper should be written in your own words. This will enable me to assess your level of understanding. In order to earn full credit, you must clearly show that you have read ALL required background materials. Be sure to cite your references in the text of all papers and on the reference list at the end. For examples, look at the way the references are listed in the modules and on the background reading list. Proofread your paper to be sure grammar and punctuation are correct and that each part of the assignment has been address clearly and completely. Length: 3 pages typed, double-spaced.

Introduction
A variable is a measure characteristic that changes whereby the independent variable(s) influence the dependent variable, and it is the effect, consequence, response or outcome. nushortage is as a result of low satisfaction, poor quality of healthcare services, low satisfaction, and poor enrollment in nursing colleges and apparent lack of respect to nurses. When seeking to collect evidence for evidence-based practice, a researcher can rely on observational or experimental studies. Control of bias influences the strength of evidence, highlighting the need to minimize risk of bias for either of the study designs chosen.
Components of this design
The study design takes into account the role of informed consent, which is essential when educating participants about their rights when participating in the study. In order to get better results it is necessary to have a large sample that would make it possible to have conclusive results and findings (Mann, 2003). Additionally, identifying the population target is essential to the success of the study as the exclusion criteria will depend on these who have already undergone through other intervention strategies. At the same time, the variables relevant to the study design are the causes and impact of nursing shortage. Even though, various factors have already been identified as the causes and effects of nursing shortage, it is important to understand how factors interact to cause nursing shortage in a hospital setting.
Observational study design
This is an observational study as it does not result to any alteration, as a researcher merely studies what occurs, ands she has no control over the environment. On the contrary, an experimental design focuses on assessment of results between the experimental and the control group. One of the ways through which to carry out the observation study is through surveys, where data is then correlated to establish whether there is a relationship between the identified variables and nursing shortage as well as the impact of nursing shortage on the workplace. The researcher cannot intervene in this study, and it is suited as there is no need to influence the population unlike in an experimental design study. A cross-sectional observational study focusing on causes of nursing shortage would highlight on quality and safety of care in hospitals, influence of the work environment on nursing shortage, patient to nurse staffing ratio, nurse satisfaction, nursing enrolment and lack of respect in the workplace.
Advantages and disadvantages of the observation design
Carrying out randomized experimentation is infeasible, and hence the design of the observational study is critical to quality of evidence provided. This design was chosen as it was the most appropriate for the...
