QCA and Fuzzy Sets for Impact Assessment in International Development and Epidemiological Contexts
Special Workshop Session on Impact Assessment Methods, June 2014. Qualitative Comparative Analysis (QCA) Grows Up: Three Surprising Applications of Fuzzy Sets-
The qualitative comparative method offers ways to interrogate data for necessary causes and sufficient causal pathways. I summarise methods of applying fuzzy set methods to the analysis of large scale and randomly sampled data, including data with control samples or treatment groups. Three new ways of applying fuzzy sets are summarised here. My special addition to knowledge is to stress how a sociologist (or development sociologist) would interpret the results. My own conclusions are based on village-level research with couples, N=39, surrounded by a survey dataset collected by Daniel Neff, which had a random sample of 187 households. In the talk, I also summarise work from Lam & Ostrom on watershed management and epidemiological treatment effect measures. Using QCA, we tease out a ranking of which causal configurations best match a sufficiency pattern for a given outcome. We can estimate the consistency level using simple spreadsheet methods but typically freeware is used for larger applications (fsQCA). Second we also develop results showing consistency of the data with the sufficiency hypothesis. Thirdly, we obtain a confidence interval around the consistency level through bootstrapping. QCA can offer good methods for studying impact because its basket of methods allow the relevance of ‘contextual factors’ to interact with treatments, and because we can perceive multiple causal pathways.

4. La suma y la resta. Propiedades
• Suma : para añadir una parte , juntar varias cantidades o
calcular el total, hacemos una suma. El primer número se
llama : sumando ,el segundo :sumando y el tercero : suma.
• La resta: para quitar una parte o saber cuánto nos falta para
llegar a una cantidad, hacemos una resta. El primer número
se llama: minuendo, el segundo número se llama :
sustraendo, y el tercero : diferencia
• Tienen las dos propiedades la conmutativa y la asociativa.
5. Recuerda
• La suma y la resta son operaciones
inversas. Para calcular el término que
falta en una suma, hacemos una resta.
Para calcula el minuendo de una resta,
sumamos el sustraendo y la
diferencia.
6. La multiplicación. Práctica y
propiedades
• La multiplicación tiene dos propiedades: la conmutativa
y la asociativa.
• La conmutativa: según el orden de los factores no altera
el producto .
• Asociativa : Cuando se suman tres o más números, el
resultado es el mismo independientemente del orden en
que se suman los sumandos.
7. La propiedad distributiva
• Respecto a la suma: ( a + b ) x c = a x c +
bxc.
• Respecto a la resta : (a - b ) x c = a x c –
bxc.
8. Práctica de la división
• Dividimos, siempre que nos quede el resto
tiene que ser menor que el divisor.
• La prueba de la división : se multiplica el
cociente ( c ) por el divisor (d) y se le
suma el resto ( r )
9. Ten en cuenta
• En una división, si multiplicamos o
dividimos el dividendo y el divisor por un
mismo número, el cociente no varía
• 1200: 50 = 120 : 5 = 24
10. La jerarquía de las operaciones
combinadas
• Siempre que aparecen operaciones combinadas es
necesario conocer qué orden debemos realizarlas.
• Primero , las de los paréntesis
• Segundo , las multiplicaciones y divisiones
• Tercero , las sumas y las restas.
