Criterion is standard of judgement or principle by which something is measured for value. Besides, normalcy is, specifically, the state of being in agreement with what is representative, usual, or regular in day-to-day activities in the life of an individual. The problem with the criterion of normalcy is that the scores for supernormality and abnormality as well be collected in what mode? The terms abnormal or normal, though used extensively in both technical and popular writing, are difficult to define precisely. Some authorities have suggested that abnormality be defined in statistical terms-that individuals who fall outside certain limits along the normal probability curve be considered abnormal.The difficulty with this definition lies in deciding where to establish limits or cutoff points. Others have suggested that normalcy and abnormality be defined in terms of cultural standards, thus allowing considerable latitude for cultural relativity. Some writers have suggested that normalcy be defined partly in subjective terms, or in terms of the individual’s feelings of adequacy, happiness, and relatedness to others. In applying such a definition, considerable latitude must be allowed for clinical judgement. The psychologists who prefer the statistical definition put forward the statement that the individual who does not differ widely from the norm or average is considered normal.A graphical sketch that which establishes limits or cutoff points at the score 50 on both sides of the normal distribution for normalcy also mention supernormal and abnormal phenomena. It can interpret normalcy and on two extremes the degree up to what extent one is supernormal or abnormal. In addition, a questionnaire that measures conscientious aspects of an individual is needed to take the scores, the positive, the negative, and both. Moreover, medical fitness is also required for normalcy.
