Learning Team Reflection
Statistics refers to the use of numerical information in everyday life to calculate facts and figures in limitless circumstances. In addition, statistics refers to the scientific collecting, classifying, summarizing, organizing, analyzing, and interpreting numerical data. This week the class’s objectives were to apply the steps in testing a research hypothesis, to compare the means of two or more groups, and to calculate the correlation between two variables. Learning Team D’s members have reflected on each of these issues and share their insights on these objectives.
Testing a Research Hypothesis
The purpose of testing a research hypothesis is to prove or disprove the research question. The first step in testing a research hypothesis is to state the problem in the form of a question. The second step is to state the research question as it relates to the null hypothesis and alternative hypothesis. Then the parameters must be set to test the null hypothesis. The fourth step is to calculate the probability of the test statistics or rejection region. Finally, the findings from the tests must be stated.
The hypothesis was familiar to one group member, so she felt comfortable with the topic. She did not struggle with any particular topic this week. This week’s topics directly relate to her field of study. As an accountant it is important to have a good understanding of mean, median, and mode, as well as statistical probability. These topics are all a part of learning to analyze information and make educated and well-thought business decisions.
Compare the Means of Two or More Groups
The experimental method of comparing the means of two or more groups is a pretty common occurrence in statistical research. The procedure for estimating and testing the hypothesis when using a single sample population will also apply in a case scenario with two or more groups or populations; however, modifications are required

The first step in testing hypotheses is to take the question at hand and turn it into a pair of theories that can be tested; the question is stated as a research hypothesis, and as a null hypothesis about the populations to be studied. The purpose behind this is to establish something to test the research hypothesis against, and essentially proving that the opposite of something is false is the same as proving that the thing is right. A prediction is made and then the polar opposite of the prediction is studied to ascertain its validity. If the null is proved wrong then the research hypothesis testing can move forward, and if it is proven to be true then the research hypothesis must be rejected.…
