1) Theories are to concepts as hypotheses are to variables. Hypotheses depend on tests that suggest multiple variables. On the other hand, theories are made up of concepts ("Theory and Practice of Social Research" 4). 2) Does a hypothesis propose a relationship between dimensions or variables? Yes. A hypothesis depends on the link that exists between two or several variables. Whereby, a slight change in variable ‘A,' leads to a change in variable ‘B.' In this case, it can be almost predictable that if the first event occurs on the first variable, then we expect variable ‘B' to ...

Importance of Confidence intervals

The confidence interval is a set or range of values that a population parameter is likely to fall within (Graham, 2008). It is calculated using the sample statistics and a given confidence level. For instance, a confidence interval of the mean calculated using the sample statistics, gives the lowest and highest possible value of the population mean. The population mean is expected to be within the confidence interval. A point estimate is a single value that approximates a population parameter (Graham, 2008). For instance, a sample mean is point estimate of the population mean, while a sample proportion is ...

Analysis of GMOs Effects on Human Health

Introduction The study of genetically modified organisms has grown to be a topic of concern in the contemporary world. In particular, there exist regulatory procedures that guide the process of approval of the genetically modified crops and foodstuffs (DeFrancesco 796). The only technique that enables the assessment of such issues is the introduction of the mechanisms like the toxicological tests, for example, in mammals, through the performance of such a process over longer time intervals incorporating detailed blood as well as organ system analysis (Séralini et al. 1). However, it has been challenging to carry out such initiatives ...

Behavioral interventions can be grouped as either antecedent-based interventions (ABI) or consequence-based interventions (CBI). CBI is a group of practices in which the problem behaviors are addressed by manipulating the reinforcement or punishment stimuli following an observed behavior, whereas ABI refers to a group of behavioral interventions that are concerned with the modification of environmental factors that are believed to precede problem behaviors (Tullis, Cannella-Malone, & Payne, 2015). Therefore, ABI strategies are implemented before the problem behavior occurs, so their unique quality is the possibility of problem behavior prevention, which makes the behavioral change easier to maintain compared to results ...

Introduction

In this report, we will critically analyze and summarize an interesting research work (Chachi, Taheri, and Viertl) related to testing statistical hypothesis when relevant data and confidence intervals are not precise. In classical Statistical inferences, we state a Null hypothesis about a precise parameter. Then, we test the validity of the Null hypothesis using classical Statistical tests using the concept of confidence intervals at some predefined level x (say 5%) based on uncertainty we can tolerate. If the value of the testing parameter lies in confidence interval 1-x, then the Null hypothesis cannot be rejected. If testing results shows ...
