Psychological and Sociological Measurement:
Psychological Measurement mainly makes use of psychological tests and inventories. Psychological test is an instrument designed to measure only a certain aspect of human behaviour. These tests yield objective and standardized descriptions of behaviour, quantified by numerical scores. These tools attempt to quantify the feelings, attitudes, opinion of individuals, etc, for example, measurement of attitude, personality, intelligence, and achievements.
Sociological Measurement attempts to measure groups or individuals in relation to a social set up. For example, Social Distance Scale which attempts to measure to what degree an individual or group or Individuals is accepted or rejected by another individual or group. The first "feeling" reactions or needs are checked without rationalizing. Socio-economic Status Scale such as SES Scale (Urban) B. Kuppuswamy, are the few examples.
