Statistical significance

Variable(s) entered on step 1: PPERSAUT, MKOOPKLA, and ABRAND. *If we look at the significance in this table for all variable is .000. This is very important and it means statistically significant factors in our model. *If we look at the odd ratio Exp (B), the rates are all over 1 which is good, it gives an idea of the magnitude of the effect…

discovered some statistical errors when I dou¬¬¬ble-checked the research for the client proposal. If these errors would change our findings and recommendations to the client, we should amend the mistakes immediately. Otherwise, our client may not only suffer substantial losses, but our firm may even lose business. Under these circumstances, I propose three recommendations for us to solve the problem. According to B.11 in the American Statistical Association’s Ethical Guidelines for Statistical…

Multiple Thresholds for Different Components of the Brain in Ischemic Stroke Perfusion Imaging Background The treatment target for acute ischemic stroke is to open the occluded blood vessel with thrombolysis. By opening the occluded vessel we can save the tissues at risk of conversion to infarct core which referred to as the penumbra. Nowadays with advanced imaging, clinicians are able to distinguish the penumbra and infarct core. If the penumbra is large and infarct core small (mismatch…

Anesthesiology has evolved tremendously since Dr. William T. G. Morton, a Boston dentist, discovered Ether on October 16, 1846 in the Ether Dome at the Massachusetts General Hospital. Anesthesiologist has important roles in many areas such as critical care, resuscitation and pain management but unfortunately the general population knowledge is limited toward the role of anesthesiologist according to many studies from different geographical areas. (1-9) Although several researches of this…

These data were collected from in-hospital and outpatient database (Nostradamus program, Madrid community health system). Statistical analysis Mean and standard deviation or median and interquartile (IQ) range were calculated, depending on distribution of continuous variable. The absolute percentage and relative frequencies were used for categorical variables. In univariate…

According to the National Campaign to Prevent Teen and Unplanned Pregnancy, in 2011 there were approximately 562,000 pregnancies among women under the age of 20 (2016). In an attempt to determine the predictors of teenage pregnancy, there were many conceptual variables to look at. These variables include delinquency, psychological factors, and aggression. Delinquency can be defined as “crimes or other morally wrong acts, illegal or immoral behavior especially by young people” (“delinquency”,…

development. In many countries, it is scientific research, rather than rich natural resources that have a direct impact on economy and development”. (Samir Al-Adawi, 2015) One must not take for granted that when an article or journal is published, the statistical methods that have been used are correct. “Unscrupulous medical research not only halts the progress of medical knowledge, but also creates unanticipated consequences. For example, this has vividly occurred in the case of concurrent…

actual NFL and other professional leagues use Statistics and data to greater lengths than ever before. This could range from organized gambling to player selection. Maximizing gambling does have its consequences if fights are rigged. For example, Statistical analysis of Japanese sumo wrestling discovered fixed fights (Data, data everywhere). That sumo wrestling league tried to maximize betting gains by rigging fights; doing so created statistically unlikely occurrences of fight results. In that…

Introduction Sloth bears are mostly found in the tropical and subtropical regions of the Indian subcontinent. Their inhabitation ranging from the foothills of the Himalayas to the southern end of the Western Ghats mountain range in India as well as in the island of Sri Lanka (Prater, 1965). The number of Sloth bear distributed in the Indian peninsula was estimated to be approximately 7,600 (Jaffeson, 1975). Two subspecies of sloth bear, namely Melursus ursinus ursinus and Melursus ursinus…

a single p-value with an accompanying FDR for the group, rather than individual significance values for each metabolite. QEA is a novel way to identify biologically meaningful patterns in metabolite concentration changes for quantitative metabolomic studies. The approach has the potential to identify subtle but coordinated changes among a group of related compounds, which may go undetected with conventional statistical…
