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 hyp Continue Reading...
The fourth step is to perform the relevant statistical test and acquire a test statistic along with its p or probability value (Iyanaga & Kawada, 1980). The fifth and final step involves making a decision to reject or not reject the null hypothe Continue Reading...
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 re Continue Reading...
