Write up for Qualitative Analysis 1. Introduction- This experiment is for qualitative analysis so we are trying to find out what is in a substance. In this case we are using the flame test to try and discover what is in 4 unknown sample solutions that we have been given this is done by cross referencing the colour of the flame with 6 known solutions we test beforehand. Aim- In this experiment we are attempting to distinguish what substances are in the 4 unknown solutions by cross referencing

1. What does the grounded study approach mean? Grounded theory relies usually relies on qualitative field observations. This means the data comes from observations on the field‚ not theoretical or following a deductive approach. 2. What group would you be interested in studying and why? What types of questions or issues‚ in particular‚ would interest you? I would be interested in learning how gangs operate‚ specifically what kind of organization they have. I don’t think most gangs are as organized

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment

Ward (1994) using interview methods in a qualitative case-study design‚ examined the special leadership practices of three elementary school principals while implementing the special education programs. The three principals‚ 2 to 3 of their regular education teachers and the entire special education staff were interviewed by the researcher and the field notes were also used the to complement the interview data. It was found that the principals had three types of leadership actions and beliefs. They

designing a qualitative study. This discussion does not replace the many excellent‚ detailed references on data collection (we refer to several at the end of this chapter). Its purpose is to guide the proposal writer in stipulating the methods of choice for his study and in describing for the reader how the data will inform his research questions. How the researcher plans to use these methods‚ however‚ depends on several considerations. Chapter 1 presents an introductory discussion of qualitative methodological
