Research Question Relationship to Research Design Lyn Shela Heck The research question or hypotheses narrows the purpose statement. It predicts what will be learned and the questions studied. A research question must indicate a target population. It must identify the dependent variable and the independent variable(s) as well as answer what is the desired knowledge or conclusion. Accurate results come from a good research question. Variables must be clearly defined. Based on the data extrapolated

Zika 'vaccine soldier” by LaMotte Sandee focuses on a woman who volunteered for a Zika vaccine experiment. Scientists have discovered a Zika vaccine, which is currently in its experimental phase. During this phase, the vaccine was shown to be effective when tested on animal. scientists are optimistic about this experimental vaccine, however they must test it out to ensure its effectiveness and safety in humans. Virginia Bliss volunteered to become a vaccine soldier to help the advancement of this

Withdrawal Design Withdrawal designs are often used in determining if the treatment is directly effecting the change in a behavior. In order to show a direct correlation between the treatment and the altered behavior, withdrawal designs remove the treatment during one or more phases of the experiment (Richards, Taylor, & Ramasamy, 2014). Withdrawal designs allow the researcher to directly show cause and effect between the behavior and the intervention treatment (Richards, Taylor, & Ramasamy, 2014)

Optimization of medium composition and culture conditions Experimental design Selection of significant variables by Plackett-Burman design The screening of significant variables influencing biomass production of Chaetoceros muelleri was accomplished by Plackett-Burman experimental design using the statistical software Design Expert (version 6.0.9, Stat-Ease Inc, Minneapolis, MN). Three nutritional parameters (nitrate, phosphate, and silicate)

conducted. The discoveries from this section provide direction to future health care providers in order to improve outcomes for patients in the clinical setting. Levels of Evidence The research conducted in this study was through a quasi experimental design, and therefore has a Level III evidence (Lee and Noh, 2016). This level contains research that was obtained via a controlled trial without randomization. This type of evidence ranks just below systematic review at Level I and randomized controlled

An Appraisal of Effects of Music Therapy on Labour Pain and Anxiety in Taiwanese First-time Mothers Carolina Escobar-Carter Georgia Baptist College of Nursing of Mercer University I have neither given nor received help on this assignment, and pledge this work to be my original composition. Carolina Escobar-Carter Synopsis This study was conducted to examine the impact that music has on primiparous women and their pain and anxiety during labor. It was hypothesized that music therapy

Is Computer Training an Effective Tool for Pressure Ulcer Classification? Mary C. Lagler Florida Southwestern State College   Is Computer Training an Effective Tool for Pressure Ulcer Classification I choose the article "Effectiveness of an e-learning tool for education on pressure ulcer evaluation" written by Laura Morente, Jose Morales-Asencio and Francisco J. Veredas. The research objective was to determine if e-learning modules were more effective than classroom training in the identification

Meanwhile, it is also beneficial to do a repeated-measure design with a pretest; this procedure could help to minimize random and unsystematic differences. Part B: Research Analyses – t-test Results and Discussion A paired samples t test with an a of .05 was used to compare mean amount of eye contact

Dilemma: Was it the right decision to withhold experimental drug PLX4032 from Mr. Ryan for the sake of following protocol and not tainting the trial’s results, even though standard chemotherapy was ineffective? Assignment 4 (I need a title) The story of Thomas McLaughlin and Brandon Ryan is of a path that suddenly diverged with a roll of a dice. As cousins, not only did they share a life together by riding dirt bikes in the summer, spending holidays together at their grandmother’s house, and even

relates to the way of a true experiment and the design that would need to be utilized by researchers within a particular case study. The second relates to the ethical guidelines that must be met by experiments as a rule and the particular experiment under consideration inside of the given case study. The third relates to the part of the Institutional Review Board, and whether the researchers in the given case study could utilize an alternate research design in order to meet the pertinent moral criteria
