sampling methods. Give one example of each. Non-probability sampling Non-probability sampling is that sampling procedure which does not afford any basis for estimating the probability that each item in the population has of being included in the sample. In this type of sampling‚ items for the sample are selected deliberately by the researcher; his choice concerning the items remains supreme. Non-Probability Sampling Methods: The common feature in non probability sampling methods is that subjective

explanations for those observations. Science assumes that biological systems are understandable and can be explained by fundamental rules or laws. Scientific investigations share some common elements and procedures‚ which are referred to as the scientific method. Not all scientists follow these procedures in a strict fashion‚ but each of the elements is usually present. Science is a creative human endeavor that involves asking questions‚ making observations‚ developing explanatory hypotheses‚ and testing

Introduction In order to identify new materials‚ scientists use a variety of chemical and physical methods to determine molecular masses. One of these methods includes the Dumas method for determining the molecular weight of a volatile liquid. This method‚ which was proposed by John Dumas in 1826‚ makes use of a volatile liquid (vaporizes at a relatively low temperature) and allows this liquid to be heated in a water bath to a known temperature and escape from a flask through a tiny opening (Giunta

RESEARCH METHODOLOGY Research Methodology is a way to systematically solve the research problem‚ it not only takes the research methods but also consider the logic behind the methods. The study of Research Methodology for developing the project gives us the necessary training in gathering materials and arranging them‚ participation in the field work when required‚ and also provides training in techniques for the collection of data appropriate to particular problems. primary objectives 1) -To

Chapter III Methodology Methodology‚ in its simplest form‚ refers to how the research should be undertaken (Saunders et al. 2009). In a practical way‚ it is a function of research question(s)‚ study approach‚ scale of the study‚ type of data‚ sample size and participants‚ data analyses techniques and study limitations (Johnson and Waterfield‚ 2004). Accordingly‚ this chapter is divided into nine sections. Section 3.1 explains the reasons for the choice of case study approach; section 3.2 describes
