There are several elements that are instrumental in the study statistics that will be discussed in this paper that include by are not limited to descriptive statistics, inferential statistics, hypothesis development and testing, selection of appropriate statistical tests and evaluating statistical results.

DESCRIPTIVE STATISTICS Descriptive statistics helps describe, show or summarize data in a meaningful way such that, for example, patterns might emerge from the data. It implies a simple quantitative summary of a dataset that has been collected, and aids statisticians and students in understanding experiments or a data set in detail and tells about the required details that help put the data in perspective. According to A. Santucci (2014), “almost all research investigations involve studying a sample of individuals randomly selected from a population with the goal of applying what is learned from the sample to all the individuals who

In order to know whether the evidence of research studies are accurate, one must be able to have a fundamental understanding in statistical analyses to determine if such descriptions and findings within manuscripts and articles are presented correctly and explicitly (Sullivan, 2012). Proper use of statistics begins with the understanding of both descriptive and inferential statistics. Correct organization and description of data characteristics from the population sample being studied leads the researcher to identify a hypothesis and formulate inferences about such characteristics. It is with inferential statistics that researchers conduct appropriate tests of significance and determine whether to accept or reject the identified null
