1) Correlation studies are a non experimental research design that measures the statistical relationship between two or more variables and to what degree the relationship exists. These studies are conducted in various environments and there is no control or manipulation in these studies. In correlation studies the researcher has more leeway with data interpretation which leads to a higher degree of bias. An example of a correlation study was conducted in Tehran in which researchers were looking for the correlation between spiritual well-being with life satisfaction and death anxiety among patients enduring cancer (Shirkavand, L et al, 2018). This study looked at spirituality with life satisfaction by itself and then death anxiety among cancer patients alone in a study then the information was combined together to see if spirituality has an effect on death anxiety.

Experimental research studies are true experiments where a variable is manipulated to determine the effect on the other variables. There is a high level of control in experimental research due to manipulation of variables for effect however. Because this type of research has more of a straight forward cause and effect the level of bias is low. An example of an experimental research study was one that was conducted using new collagen sponge scaffold (NCSS) combined with adipose-derived stem cells (ADSCs) in the repair of full thickness skin wound (Zhang, A. et al, 2018). This study used a tissue engineered skin to promote advance healing of full thickness skin wounds versus the standard wound healing methods to determine which would heal wounds faster. The standard wound treatments were the control and the new engineered skin was the variable that the other treatments were compared to.

Re: Topic 3 DQ 1

Experimental and nonexperimental are methods that have some similarity. They are both important because they provide specific hypothesis about the data but different in predictability.

Experimental research provides strong evidence which can create a clear change in independent variables. It evidently cases a difference in the effectiveness of the data and creates a more reliable and dependable analysis. It is a source of research that is mainly used by researchers that correlates with evidence-based practice.

Nonexperimental research is not as reliable in experimental research, but it is still verified as providing a kind of data that deemed effective with substantial amount of validity for researchers to use and they use it to obtain specific data collection between variables. They provide different trending patterns that is observed carefully between the two data.

Randomization design is considered unpredictable but can sometimes be useful to verify simplified experimental data, this includes evaluating certain measures of treatment and procedures. Research have shown more emphasis is placed on experimental data to conduct a scholarly approach to health care research.

Re: Topic 3 DQ 1

Experimental research design is a type of quantitative research design that is highly controlled and to study cause and effect with independent and dependent variables (GCU, 2018). For example, comparing the scores of knowledge about pressure ulcers from staff who participated in the educational course with the staff who did not attend the educational course. The results confirmed the hypothesis of the study that professional nurses participating in educational courses on pressure ulcers have higher knowledge scores than those who do not participate (Baron, et al., 2016).

Nonexperimental research measures the statistical relationship between two or more variables and the degree of the relationship (cause/effect) (GCU, 2018). An example of nonexperimental research Consists of cross-sectional research, correlational research, an observational research. Nonexperimental research is done without any interference or manipulation from the researcher. For example, a researcher randomly assigned patients with low back pain either to a treatment involving hypnosis or to a treatment involving exercise. measures are taken to evaluate their level of low back pain after 3 months (Price, Jhangiani, & Chiang, 2015).
