Bottom Line
QCA makes it possible to bring the logic and empirical intensity of qualitative approaches to studies that embrace more than a handful of cases -- research situations that normally call for the use of variable-oriented, quantitative methods.

Qualitative Comparative Analysis (QCA) is a new analytic technique that uses Boolean algebra to implement principles of comparison used by scholars engaged in the qualitative study of macro social phenomena. By formalizing the logic of qualitative analysis, QCA makes it possible to bring the logic and empirical intensity of qualitative approaches to studies that embrace more than a handful of cases -- research situations that normally call for the use of variable-oriented, quantitative methods.
fsQCA makes the following assumptions about the structure of *.csv, *.dat and *.txt data files. First, and most important, fsQCA assumes that the cells in the first row of the spreadsheet contain variable names for their respective columns. Second, fsQCA assumes that the data begin in the second row of the spreadsheet and that each case is a single row.
Finally, fsQCA assumes that each column contains cells of the same type of data. Once users have their data in the fsQCA program and have completed some preliminary analyses, users have the option to either edit the data in fsQCA (see Chapter2), or edit their data with the help of software packages users are more familiar with (i.e. SPSS or Excel). Similarly, users can either display the data graphically with the fsQCA program or turn to SPSS or Excel for more elaborate graphical representations.
If users choose SPSS or Excel for these operations, users need to save the fsQCA file and transfer it to the program of their choice. FS/QCA can read comma, space, or tab-delimited file. The more recent versions of SPSS will create tab-delimited files with variable names on the first line of the data file. This file type is best for FS/QCA and allows a relatively painless back and forth between SPSS (for data transformation, etc.) and FS/QCA (for analysis).

Qualitative Comparative Analysis (QCA) is a modern analytic technique that utilizes Boolean algebra to effect principles of comparison used by scholars performing research on social phenomena. QCA helps qualitative statisticians perform both intensive and integrative analyses i.e. addressing many aspects of cases and examining how the different parts of a case fit together, both contextually and historically.

ADDITIONAL INFORMATION By formalizing the logic of qualitative analysis, QCA makes it possible to bring the logic and empirical intensity of qualitative approaches to studies that handle multiple research cases that normally call for the use of variable-oriented, quantitative methods. Boolean methods of logical comparison represent each case as a combination of causal and outcome conditions. These combinations can be compared with each other and then logically simplified through a bottom-up process of paired comparison. Computer algorithms provide techniques for simplifying this type of data. The data matrix is reformulated as a truth table and reduced in a way that parallels the minimization of switching circuits, helping make multiple comparisons of configurations. What logical minimization seeks to achieve is to represent, in a shorthand manner, the information in the truth table regarding the different combinations of conditions that produce a specific outcome.
