A case study may combine a variety of data collection methods and research strategies (Fellow and Liu, 2003). It is the only prime implicant that covers the minterm denoted by decimal 10 and it also includes the terms 0, 2 and 8. These prime implicants are then examined to see if some are redundant. Table 3.4 provides the road map utilised to implement the present research work. Jain * SAMPLING METHOD is an important tool in the realm of social science researches.

A larger sample size lowers the likely error in generalizing the results from the sample to the population (Saunders, Lewis and Thornhill 2000). Also Check: Tabular Presentation of Data. Care must be taken to fill in every cell with the relevant entry, such as a 0, 1 (or) don’t care terms. The combination of the two approaches is termed triangulation. Explanatory research aims to explain why a phenomenon occurs. inverted form by 0, and the abscence of a variable by a dash ( - ). Need for subject specific knowledge 4. changeability of sampling units 5. impossibility of sampling. A sample is used to gather information about the variable. 3. *You can also browse our support articles here >. According to Yin (1994), four tests are commonly used to establish the quality of any empirical social research such as construct validity, internal validity, external validity and reliability. A sampling frame is a list of the population from which sampling units are drawn (Hussey and Hussey 1997). The tabular method which is also known as the Quine-McCluskey method is functions. To fulfil the purpose with this thesis, both exploratory and descriptive approaches have been chosen. 3b.Development of Sustainability Assessment methodology based on composite sustainability performance index. Descriptive research involves examining a phenomenon to define it more or to differentiate it from other phenomena (Dane, 1990; Martella et al., 1999).
