The class-frequencies chosen in the census for tabulation of statistics of infirmities—19. Inclusive and exclusive notationsand terminologies. 1. THE methods of statistics, as defined in the Introduction, deal with quantitative data alone. The quantitative character may, however, arise in two different ways. In the first place, the observer may note only the presence or absence of some attribute in a series of objects or individuals, and count how many do or do not possess it. Thus, in a given population, we may count the number of the blind and seeing, the dumb and speaking, or theinsane and sane. The quantitative character, in such cases, arises solely in the counting. In the second place, the observer may note or measure the actual magnitude of some variable character for each of the objects or individuals observed. He may record, for instance, the ages of persons at death, the prices of different samples of a commodity, the statures of men, the numbers of petals in flowers. The observations in these cases are quantitative ab initio. 2. The methods applicable to the former kind of observations, which may be termed statistics of attributes, are also applicable to the latter, or statistics of variables. A record of statures of men, for example, may be treated by simply counting all measure- ments as fall that exceed a certain limit, neglecting the magnitude of excess or defect, and stating the numbers of tall and skort (or
