In order to answer the research questions, it is doubtful that researcher should be able to collect data from all cases. Thus, there is a need to select a sample. This paper presents the steps to go through to conduct sampling. Furthermore, as there are different types of sampling methods, researcher needs to understand the differences to select the proper sampling method for the research. This paper also present different types of sampling techniques and methods. "Hypothesis testing is an integral and the most important part of the Research Methodology". In this paper, we introduce the overview of hypothesis and types of hypothesis. Researcher need the perfect method to reach towards the best conclusion so we also discuss the hypothesis testing steps, and various tools used for hypothesis testing so that researcher can take a perfect decision
