The hypothesis is “a testable statement of a relationship; an epidemiologic hypothesis is the relationship between the exposure (person, time, and/or place) and the occurrence of a disease or condition” (Grand Canyon University, 2018, para 9). In healthcare, there are always questions being asked about how to improve quality of care. These questions are the first step in research to form the question that defines the hypothesis. The hypothesis is a forecast of what will occur between variables the independent and the dependent variable. The hypothesis identifies both variables; data is collected based on these, the research process shows connection or relationship but does not prove causation.

An example of a hypothesis is the health benefits of cannabidiol (CBD) oil in patients with lupus. There is no study to prove or disprove the benefits to lupus patients of taking CBD oil. The null for this hypothesis is the patients with lupus who take CBD oils have less pain and fatigue. The alternative hypothesis would state that patients with lupus do not experience any changes in symptoms with the use of CBD oils.

Another example is neurologic music therapy training for patients with Parkinson’s disease. The hypothesis is the music will help improve the stability and mobility of the patient with Parkinson’s disease. The null for this hypothesis is there is no change in stability or mobility when the patient with Parkinson’s disease listens to music while walking. The p-values were higher than 0.05 in the two groups without music, with music the p-values changed to <0.05 the null hypothesis is rejected because there is a statistically significant difference between the two groups (Bukowska, Krężałek, Mirek, Bujas & Marchewka, 2016).

Evidence-based practice is used for problem-solving questions in health care about safe practices. The systematic approach to identifying the most pertinent evidence to implement change that will improve patient safety and the care of the patient requires the nurse to use critical thinking and an understanding of how to apply statistical data to nursing skills and patient care (Grand Canyon University, 2018).
