Major Statistics Assignment
This major statistics assignment will finally pull together everything that was learned in this course. The application of all content within this course will be incorporated to three different research scenarios. Within each scenario, hypothesis testing will be done, followed by a discussion of relevant descriptive statistics and finally, a discussion of the findings which includes nursing practice implications and research implications. Research Scenario #1

In this research scenario, the researchers were interested in the following research question: “Is there a difference in nurses’ abilities to identify nursing skills that reflect knowledge of client centered care values of A) respect and human dignity B) consistency, continuity and timelessness of care or C) patient autonomy, patient voice and patient as decision maker.” To answer this research question, a hypothesis testing will be conducted followed by a discussion of the findings. The discussion of the findings will include a discussion of descriptive statistics, followed by nursing and research implications. Hypothesis Testing

Step 1. The first step in hypothesis testing is to state the null and research hypothesis. The null hypothesis can be: “There is no difference in the nurse’s abilities to identify nursing skills that reflect knowledge of client centered care values of A) respect and human dignity B) consistency, continuity and timelessness of care or C) patient autonomy, patient voice and patient as decision maker.” Conversely, the research hypothesis is “There a difference in the nurse’s abilities to identify nursing skills that reflect knowledge of client centered care values of A) respect and human dignity B) consistency, continuity and timelessness of care or C) patient autonomy, patient voice and patient as decision maker.” The target population in this study are nurses who provide client centered care, while the sample population is the 39 nurses in the ICU, in one teaching hospital in Southern Ontario who participated in this study.

The independent variable (IV) in this study is the client centered care values, which are A) respect and human dignity B) consistency, continuity and timelessness of care or C) patient autonomy, patient voice and patient as decision maker. While the dependent variable is the actual knowledge scores measuring the nurses’ abilities to identify nursing skills. The IV in this study would be nominal because the three groups within the IV are only categories that do not have any numerical values attached to them (Salkind, 2007). Therefore, they cannot be ranked or ordered in any way, making it nominal (Salkind, 2007). Conversely, the DV in this study would be interval, because the abilities to identify the nursing skills are given scores from 0-10, where 0 represents “poor to no knowledge” and a score of 10 is “excellent knowledge.” Although a score of “0” is present, this does not indicate an absolute zero or an absolute absence of knowledge; therefore it cannot be ratio.

Lastly, the test to be done is a one-way ANOVA or a simple ANOVA. This is because there are three groups within the IV, wherein we are interested in determining the differences in the mean scores across these groups (Salkind, 2007).

Step Two. The level of significance that will be used is p<0.05. This is because no potential harm is being posed to the participants (Salkind, 2007). In addition, there this means that I am accepting the fact that there is a 5% chance that I reject the null hypothesis, when in reality, it is true (Salkind, 2007).

Step Three. The third step into the hypothesis testing is to choose either a one-tailed or a two-tailed test (Salkind, 2007). In ANOVA however, choosing a one-tailed or a two-tailed test is not applicable. This is because an F test simply...
