Statistical inference

in metaphorical language use of the experimental group and the control group at the beginning of the metaphor awareness treatment, an independent samples t-test was conducted for the data gathered from the participants’ recent writing test. The statistical analysis indicated that there was not a significant difference in the metaphorical language use of experiment group (M = 1.59; SD = .70) and control (M = 1.44; SD = 1.00); t (43) = .58, p = .56. Levene’s test for equality of variances was…

is control by other parties. The almost the same results are for the states which do not have death penalty (64,79% and 35.21%, respectively) With a Person Chi2 of 0.2091, a p value of 0.647 and a degree of freedom equivalent to 2, there is not statistical significant relationship between these two…

No one will argue that determining the number of significant figures and keeping with the rules of those “sigfigs” throughout an already strenuous calculation can be a pain. Countless points and half-points have been deducted from tests throughout chemistry’s ages from students claiming that significant figures are, ironically, insignificant. But, let’s consider the following scenario. Joey is in his inorganic chemistry lab. The second step to the lab tells him to measure out the mass of Iron he…

PICOT For nurses at the Clinica Las Mercedes caring for adult Hispanic diabetic patients does the implementation of the Chronic Care Model (CCM) with Diabetic Self-management Education (DSME) program lead to improved diabetes management and self-care knowledge in eight weeks? 1. Sample The study will be conducted in a major primary care facility, which is chosen based on convenience. All the registered nurses in the hospital’s medical and surgical wards comprise the target population. The study…

Question 1 Cowles and Davis (2016) discussed several factors that contributed to the adoption of the .05 level of statistical significance. The first factor discussed was the discovery that computations can be utilized to measure observational error, by and astronomer, Lambert Adolphe Quetelet. This discovery led to the development of the normal distribution curve utilized today (Cowles & Davis, 2016). Following the development of the normal distribution curve, a measure of variability known…

to grow in all countries with the only difference in period when the impact reaches its peak. However, not all impulse response functions are statistically significant. In this paper statistical significance is tested by analysing confidence intervals. It has become standard in relevant papers to evaluate statistical significance using upper and lower limits of impulse response functions. “An easy way of assessing whether any of these responses is significantly different from zero is to search…

A fever is not an illness, but rather an indication of an underlying problem or cause within the body. It is characterized by an elevated core temperature measuring above 100°F (37.8°C).1 This increase in temperature is controlled by the hypothalamus, which raises the thermoregulatory set point in order to defend the body.1 Fevers are a great concern in infants, with more children having reported fevers compared to adults.1 Acetaminophen is both a prescription and an over-the-counter medication…

using the one-way ANOVA, is the following: Does the frequency in days of the week make a difference in having an ideal body weight? The one-way ANOVA is the most appropriate statistical test as the question identifies an independent variable that can have up to a maximum of 7 groups, to represent the days of the week. The statistical notation is the following: F = MSbet MSwith (Sukal, 2013, Formula 6.4) The null hypothesis would be the following: The frequency in the days of the week does…

Results In the univariate analysis factors race and side proved to be insignificant by the Wald test at 5% significance level. Hence the eruption sequence does not significantly differ among the Races and remains unchanged between left and right side in the mouth. Then a multivariate CoxPH model was fitted using variables District, SS, gender, jaw and type which were the significant variables in the univariate analysis. These five variables continued to be significant in the fitted multivariable…

Exercise 7 (set 1) 1. What are three versions of the null hypothesis? The three versions of the null hypothesis are: (1) “the observed difference was created by sampling error”, (2) “there is no true difference between the two groups” and (3) “the true difference between the two groups is zero.” (Barker, 56-57) 2. Is the null hypothesis typically stated in social scientific research? Why/why not? The null hypothesis is not usually stated in social scientific research. Researchers rarely state…
