Bottyán, O.: An analysis of the palatal measuring methods
a heterogeneous sample (Europoide, Australoide, Mongoloidé, Negroide) comprising 33 adult individuals, she calculated the correlation between the lengths established by the classical and the HEiNTZ-method, and showed that r = 0.85, which gives a significant correlation. At the same time, r = 0.1 for the two kinds of breadth, indicating uncorrelatedness. It should be noted that HEINTZ was careful to select samples with regular dental arcs and second molars with a constant character. HEINTZ then calculated the correlation between the length and breadth of the palate by both the classical measurements and those proposed by her. The classical measurements resulted in r=— 0.06, that is, complate uncorrelatedness, and in r = 0.45 by the new method, revealing a significant correlation. With respect to these latter two r-values, she remarked that the suggested new measuring method "brought certain phenomena to the surface which remained concealed by the classical measurements. That which is to be observed in the classical measurements, namely their total independence, is probably nothing else but indicative of their faultiness." The problem now justly arises whether the palatal lengths should actually be in correlation with the breadths, or rather, should the two measurements be independent of one another. On the basis of the correlational coefficients found by HEINTZ and the number of individuals of the sample, I attempted to estimate the orders of magnitude of the corresponding probability levels. The correlation of the relationship (Table I, No. 1) has such great values that its probability level cannot be estimated by simple mathematical methods. The probability level of the correlation of relationship No. 4 is 10-2 (that is, there are 99 correlations in one hundred cases). Eor the other two correlations (Nos. 2, 3), HEINTZ found uncorrelatedness. The Hungarian sample and the results of its study I have examined some bigger series originating from Hungary, and in most cases already published. They derive from the period IV B.C. — XVI A.D. (Fig. 1). The localities are as follows: Szabadszállás —Józan, IV cent. B.C. (DEZSŐ, 1966); Majs, III—IV cent. B.C. (ERY, MS); Hegykő, VI cent. A.D. (TÓTH, 1964); Szebény, VIII cent. A.D. (TÓTH,
