Quantitative and Qualitative Methods of Research

Measurements of data in a big population are carried out through random sampling. Random sampling does not give an accurate measurement in people since people are different from each other as compared to elements tested in natural sciences that are always identical (Graham, 2008). The best approach to measurement that should be used in the measurement of people and society is the use of a computerized sampling method that is programmed to practice simulation. Use of computerized sampling will ensure that the whole population is well represented (Davies, 2007). Both qualitative and quantitative types of research need to be valid and reliable to enhance their use by analysts. The validity of these research methods ensures the connection of the research carried out and the theoretical ideas of the researcher (Chikkodi and Satyaprasad, 2010). Much of it refers to the generalizability of the findings in both the quantitative and qualitative research. In a bid to assess, the validity of these two types of validity in research, their credibility and transferability aspect is very important (Connaway and Powell, 2010). The credibility aspect is used to determine whether the findings in the research seem believable while the transferability aspect determines whether the findings of the research are applicable in another context. Reliability of these types of research refers to the situation in which more than one observer of the study agrees with the findings (Katsirikou and Skiadas, 2012). A good example is how an efficient apparatus in laboratory gives accurate data.
