Discovering patterns1)Qualitative analysis involves the nonnumerical examination of observations in order to discover underlying meanings and patterns of relationships.Compared to a researcher doing quantitative data analysis, a researcher doing qualitative data analysis is ----- likely to go back and forth between data analysis and theory.LessMore2)Sometimes qualitative research is undertaken for descriptive purposes, but often there is an attempt to search for an explanatory pattern to a phenomenon. In searching for patterns, a common technique is to use a cross-case analysis. Which of the following best describes cross-case analysis?An analysis that involves an examination of more than one caseAn analysis that follows the story of a case using a lot of relevant and descriptive detailsAn analysis undertaken to determine how the occurrence of one event correlates with a particular outcomeAn explanatory analysis of a person, group, or event3) If, however, you choose to conduct a case-oriented analysis, which of the following should you keep in mind?This type of analysis provides the ability to derive theories about people in general.This type of analysis tells you nothing about people in general.You will need to keep careful notes due to the number of cases under study.You will want to analyze the least number of variables as possible
