Mill's Methods are five methods of induction described by philosopher John Stuart Mill in his 1843 book A System of Logic. They are intended to illuminate issues of causation The methods Direct method of agreement. If two or more instances of the phenomenon under investigation have only one circumstance in common, the circumstance in which alone all the instances agree, is the cause (or effect

23.12.2013· 'Ball milling is a method used to break down the solids to smaller sizes or into a powder. A ball mill is a type of grinder which consists of a cylinder. It is used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. The cylinder rotates around a horizontal axis. It is partially filled with the grinding medium and the material to be ground. Materials

Snowball Sampling Method . The nature of snowball sampling is such, that it cannot be considered for a representative sample or in that case for statistical studies. However, this sampling technique can be extensively used for conducting qualitative research, with a population that is hard to locate.
