¶ … testing a hypothesis is to establish one. There should be a null hypothesis that the data can be used to test. Data acquisition is therefore the next step in testing the hypothesis. The data needs to relate directly to the hypothesis with a clear relationship that can be subjected to quantitative analysis. Quantitative analysis will then measure the relationship between the variables to determine whether or not the data fits with the null hypothesis. The null hypothesis is then either accepted or rejected on the basis of the analysis (Investopedia, 2013). Further, the null hypothesis should identify the dependent and independent variables. The dependent variables are those that will be measured in relation to change in the independent variables. Thus, it is the independent variable(s) that will be changed to measure the effect that change has on the dependent variable(s). There may also be an alternative hypothesis, which may simply be to reject the null hypothesis. The method of quantitative analysis must be determined. There are a number of methods to choose from, and usually the choice must be supported by research that shows such a method is an appropriate means of testing that type of hypothesis using that specific type of data. Regression is usually used to measure correlations between independent...
Testing Ethical and Legal Issues Considering the responsibilities and rights of test takers and test users, discuss why it is important to have ethical and legal standards for testing. What knowledge, skills, and abilities are necessary for competent test use? What are the standards regarding confidentiality and privacy of test taker information, test scores, and test interpretation? What do you feel is the most important responsibility of a test user and why?
The employee's imperative is bound by the employee's desire to maintain employment. To the business, however, there is a competing imperative in that it must increase profits. For the cost of a test, the business can prevent a certain degree of losses. Thus, from the businesses perspective its imperative, if applied evenly and universally, would compel it to reject testing of its executives just as much as it would
Level 2: Beginning: Children can make use of simple phrases. Level 3: Developing: Children exhibit hesitant use of written and spoken academic and social English. Level 4: Expanding: Children show comfort with social English, while have difficulty with academic English. Level 5: Bridging: Children are capable of understanding both academic and social English with competency, although with some difficulty (Law & Eckes 2007, p.47). The question of whether an incoming
Testing Hypothesis The first step to testing a research topic is conducting a literature review to determine what has been researched, any gaps, or any inefficiencies in the research studies. The literature review aids in determining appropriate hypothesis, variables that need to be studied, and appropriate research study methods and designs. Depending on the research methodology and designs as well as the goals of the researcher, appropriate confidence intervals can be
Testing Describe one ethical issue surrounding the Uniform Care Requirement, which requires that all participants of clinical research across the world should receive the same treatment that they would in a Developed country. The Uniform Care Requirement has been proposed as a "minimum ethical standard" but profit-driven researchers claim it may conflict with other ethical standards in making HIV / AIDS medications available to more people in the developing world (Killen, Grady,
This type of research suggests that there is a correlation between general intelligence (g) and physiological factors such as development stability and general physical fitness. One might develop the research question further by investigating whether intelligence can be manipulated by means of increasing actual physical fitness levels by means of exercise, for example. Since it has long been an accepted fact that the body and mind function as a mutually
