¶ … 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...
ANOVA is a technique that can be used with smaller data sets in Excel. For larger and more complex data sets, SPSS is typically used. A number of test statistics are derived from the data and then these are converted, in theory, to meaningful data regarding the hypothesis (No author, 2013).
The output of quantitative analysis will consist of a number of different measures, each of which has its own meaning that must be interpreted. These meanings include fit, statistical significant and confidence intervals. The different output figures are challenging to interpret, because there is very little information in English -- too many sources talk too much about the math and it becomes difficult to understand the difference between, say "confidence interval" and "significance," which sound like pretty much the same thing.
For basic, non-ANOVA analysis, the metrics are easier to understand. Comparing the means of two or more groups is a very basic quantitative technique, but one that is also relatively poor when trying to find the links between different variables. Means may be used where the underlying variables are very similar, but preferably a…

Management Strategy to Utilize Meta-Analysis Technique for Nuclear Energy and Waste Disposal and Create Social Sustainability This research proposal explores the link between public perceptions of nuclear power, how those perceptions are formed, and what influence those opinions have on energy policy. These issues are important in light of two realities. First, nuclear energy is declining in its share of global energy. Second, nuclear energy offers what might well be
Establishing an NP Led Wellness and Recovery Center for Deinstitutionalized Individuals Historically, nursing, and medicine professions have been loath to utilize tools commonly linked with mercenary aspects of business, such as market research and decision analysis. In the contemporary health care setting, however, consumers hold numerous options for care providers. The division of the market or market segmentation into different subgroups allows the determination of target markets and the buildup of
Transient Vibrations and Shock Loads in Spacecraft Components Increasing performance, as well as the goals of reducing costs, have been the major factors affecting the design of the present and future spacecraft launching system. However, the level of vibration is currently affecting the design process, and launch phase, which may lead to a satellite failure. While it is possible to design the spacecraft to withstand the loads, it is still

-Provide an example of a hypothesis where a one-tailed hypothesis test would be used. An example of a one-tailed test is testing the claim that the mean score of the gender male is higher than the scores of the gender female in public institutions. -Provide an example of a hypothesis where a two-tailed hypothesis test would be used. An example in this case is testing the claim that the mean scores between the gender male

Retrieved on July 27, 2004 at http://www.trianglenet.net/~weeks/nba/nbasalary.htm One common assumption in economics is that salary is directly related to quantitatively established aspects of job performance and the quality of one's education and occupation. But is this true of all professions? To take one extreme case to make a larger point, the example of NBA players
