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. The steps in testing a research hypothesis, to compare the means of two or more groups, and to calculate the correlation between two variables.
Testing a Research Hypothesis
The hypothesis process has five steps. It is necessary to follow these steps to research any issue or question. Not following the steps or conducting them out of order could result in poor results. The purpose of testing a research hypothesis is to prove or disprove the research question. ("Research Hypothesis", 2015). The five steps involve stating the research question, clarifying null or alternative hypothesis, experimentation and calculating, evaluation of experimentation, and the conclusion of the results. The first step consists of stating the research question. The second step consists of defining the null and alternative hypotheses as well as selecting a level of significance. The test will be usually done with a significance level of α = 0.05, which is a typical value used in business-related hypothesis testing. ("Statistical Hypotheses", 2014). The third step corresponds to identifying the appropriate test statistic. This is done based on the size on the sample. During step four, the research formulates a decision rule taking the level of significance, and the test statistic into account and the data is analyzed. Finally, in step five, conclusions are determined as to whether the null hypothesis is true or the alternative hypothesis is true.

The experimental method of comparing the means of two or more groups is a pretty common occurrence in statistical research. The procedure for
