Statistical significance

This paper will review the studies used to obtain statistical data showing the effects cinnamon on glycemic control in adolescents with type 1 diabetes. The article summarizes how seventy two adolescents type 1 subjects were treated in an outpatient setting with cinnamon, 1g/day, or an equivalent placebo for 90 days (Altschuler, 2007). During this time, A1C levels, total daily insulin use, and any adverse events were recorded and compared. This article created two distinct testing groups. One…

Respiration Rate Analysis on Goldfish While Being Exposed to Varying Water Temperatures Avarie Wideman, Bronwyn Edgell, Brooke Farrell, Shannon Porter & Emma Milne 1 Uxbridge Secondary School, Uxbridge, Canada ________________________________________ Results After completing the goldfish respiration experiment we were left with an abundance of data that has lead us to these results. Through the experiment we have discovered that the goldfish's respiration is affected when exposed to extreme…

oil were able to cut the number of eggs present by almost half. However, the analysis of the error bars showed no significance between the no sunflower oil and sunflower oil of either 5ml/kg or 15ml/kg concentration. This lead to the conclusion that while sunflower oil is capable of deterring C. maculatus from laying eggs on beans treated with the oil, the lack of statistical significance indicates that sunflower oil is an ineffective way to control the population of C. maculatus. Therefore, the…

The search for the origins of humankind and the earliest human ancestor has intrigued anthropologists for generations. New evidence, while often scarce, is a vital aspect to the understanding and development of the field of paleoanthropology. Current research aids in the modification of the human ancestral tree and the analysis of various sites. One of the newest sites dealing with human evolution is the Rising Star cave system in South Africa, where a new species of human ancestors, Homo naledi…

cranberry, and pomegranate powder on a per gram basis. The total polyphenol content (Figure 1B) of cocoa powder (48.2 ± 2.1 mg/g) appeared to be greater than acai, blueberry, and cranberry powder; however these differences did not reach statistical significance. The total flavanol content (Figure 1C) of cocoa powder (30.1 ± 2.8 mg/g) was significantly greater than all of the other fruit powders tested. There were no other statistically significant differences in antioxidant capacity, total…

Lawson, Andrea, and Gregory Fouts. "Mental illness in Disney animated films." Canadian journal of psychiatry 49.5 (2004): 310-314. Web. 20 Jan. 2016. In this research paper, Lawson and Gregory illustrate their study on the prevalent verbalizations of mental disabilities in Disney moves. Their main claim is that these verbalizations lead to children’s negative attitudes toward disabled people in reality. Based on the result of their research, they proposes sub-claims. Their first sub-claim is…

Each research question specified the problem and identified issues that lead to a need for the study. Each study provided a qualitative purpose statement using the research questions, which provides the major objectives to the study. The processes required for developing effective qualitative research questions can give shape and direction to a study in ways that are often underestimated. Both studies provide research questions that narrowed the purpose by placing subdivided fundamental…

Analysis Methods (specify statistical analyses used) Data is collected, hand-scored, and entered into SPSS file. Researchers analyze the data using two methods to examine the relationships between spirituality, stress, and physical symptoms. The tools used to analysis the data are the correlational analysis and the regression analysis. The correlation analysis assesses the relationship between spirituality and forgiveness; whereas the regression analysis uses statistical figures to take stress…

Summary of Study Hypothesis. Leichsenring and Leibing (2003) addressed several questions in their study: What is the evidence of improvement in symptoms, social functioning, or core psychopathology after psychodynamic therapy or cognitive therapy? Is there evidence of improvement in specific types of personality disorders after psychodynamic therapy or cognitive behavior therapy?, Do individuals with personality disorders recover after psychodynamic therapy or cognitive behavior therapy? Are…

tests. There are some test types: Message tests, Aha moment test and large scale design tests. 5 Measure success Due to we already started our test, we need to evaluate the outcome carefully. And then decide what’s the next. 95% statistical significance and 80% statistical power could be a Better benchmark for evaluate. We should measure impact through the entire funnel, not for page level. The bigger data changes yield faster results. Obviously everyone wants to optimize the results of their…
