Next, comparison is a central process to all data analysis, qualitative or quantitative. All social researchers compare features of the evidence they have gathered internally or with related evidence. Researchers identify multiple process, causes, properties, or mechanisms within the evidence.They then look for patterns-similarities and differences, aspects that are alike and unlike.
Fourth, in both qualitative and quantitative forms of data analysis, researchers strive to avoid errors, false conclusions, and misleading inferences. Researchers are also alert for possible fallacies or illusions. They sort through various explanations, discussions, and descriptions, and evaluate merits of rivals, seeking the more authentic, valid, true, or worthy among them.
