AND CODE QUALITATIVE RESEARCH METHODS IN PSYCHOLOGY (PSY 212) LECTURER MR MATIKA ASSIGNMENT QUESTION: “Qualitative research methods are designed to help researchers understand individuals‚ the social and cultural context within which they stay. Understanding the phenomena from the point of view of the individual and its particular social and institutional context is largely lost when textual data is quantified” (Myers‚ 1997). Discuss the above statement in relation to qualitative and quantitative

physical and chemical properties which dictate their uses and applications. Furthermore‚ this kind of analysis is important in quality control since the detection of unwanted chemicals may lead to the rejection of a product for example. In addition to qualitative identification‚ quantitative analysis can be performed to determine the quantity and concentration of chemicals. This is arguably as important since it is essential in order to do any kind of quantitative calculations. Furthermore‚ determining concentration

Initial post Comparing Qualitative and Quantitative Approaches Researchers often times are faced with the decision of choosing a methodology of research; either Quantitative or Qualitative that they think best fits their study and objectives. This choice is guarded by the topic of study‚ the advantages and disadvantages‚ and the strengths and weaknesses of using either one or the other type of the methodologies. Researchers are sometimes using Quantitative and Qualitative research methodologies interchangeably

Qualitative vs Quantitative analysis Qualitative analysis: Richness and Precision The aim of qualitative analysis is a complete‚ detailed description. No attempt is made to assign frequencies to the linguistic features which are identified in the data‚ and rare phenomena receives (or should receive) the same amount of attention as more frequent phenomena. Qualitative analysis allows for fine distinctions to be drawn because it is not necessary to shoehorn the data into a finite number of classifications

Introduction The purpose of this experiment was to find the identity of the unknown compound #12. This was done both qualitatively and quantitatively. The qualitative observations were used to determine the functional group that was in the unknown‚ the quantitative results were used to determine the molar mass through Duma’s method. The types of compounds that were used in testing were all functional groups‚ Aldehyde‚ Ketone‚ Alcohol and‚ Ester. Functional groups are a portion of a molecule that
