For a number of years the writer has been conducting a continuing economic study of the petroleum industry, based partly upon the rela? tively ample statistics with which this field is favored and partly upon the technology involved in the production, refining, and utilization of petroleum.* In order to ascertain whether the course of petroleum shares on the stock market is influenced by economic conditions peculiar to petroleum or is wholly a function of the forces common to the movement of industrial shares in general, a price index of oil stocks has been prepared and will be maintained. A brief description of the method employed and the results attained is herewith presented. The preparation of a practical stock index involves greater difficul? ties than many other types of indices, owing to the rapidity and the degree of scatter characteristic of the individual quotations, and the tendency of some of the items to die away and thus "load" the index with inactive components. The conventional type of index as cal? culated by financial journals and consisting merely of an arithmetic mean of a selected number of quotations is a crude expedient, as has been critically shown by Wesley C. Mitchell.f The main trouble with this type of index is that it is dominated by the more vigorous of its components and is, therefore, not a representative index. Obviously, if the more vigorous and more costly stocks are not to dominate in an index, the items must be weighted. The weights may be assigned directly to the items or introduced indirectly by converting the quotations into percentages of a fixed base. The latter method was preferred because it affords a double comparison and lends itself to convenient treatment.
多年来，笔者一直在对石油工业进行持续的经济研究，其部分依据是石油工业的发展状况。这一领域受到青睐的充分的统计数据，部分取决于石油生产、提炼和利用所涉及的技术。*为了确定股票市场上石油股票的走势是受到石油特有的经济条件的影响，还是完全受工业股票一般走势的共同力量的影响，我们编制了一个石油股票价格指数，并将予以维持。现就所采用的方法和所得的结果作一简要说明。编制一个实用的股票指数涉及更大的困难?由于个别报价的迅速和分散的程度，以及一些项目逐渐消失的趋势，从而使指数“负荷”了不活跃的成分，因此，指数比许多其他类型的指数都要高。传统的索引类型是cal?正如韦斯利·c·米切尔(Wesley C. Mitchell)批判性地指出的那样，由金融期刊编制的数据，仅仅由选定的引文数量的算术平均值组成，是一种粗糙的权宜之计。f这类指数的主要问题在于，它是由更有活力的成分股主导的，因此不是一个具有代表性的指数。显然，如果不想让更有活力、更昂贵的股票在一个指数中占据主导地位，就必须对这些股票进行加权。权重可以直接分配给项目，也可以通过将报价转换为固定基数的百分比来间接引入。后一种方法是首选的，因为它提供了双重比较，并使自己方便的治疗。

A statistical series may be assigned to one of two broad classes according as it consists merely of a list of numbers of indefinite arrangement, or has its items ordered relative to a particular variable. Typical of the first class are the series composed of experimental measurements, and chief illustrations of the second class are to be found in historical series in the field of economic statistics. The common statistical coefficients have been developed in the study of, and are peculiarly applicable to, series of the first class; and i t is a question of considerable moment whether such coefficients are equally useful in the analysis of an ordered series of the second class. The chief measure of dispersion is the standard deviation, the square root of the mean squared deviation from the arithmetic mean. It is apparent from the method of calculation of the standard deviation that it can take no account of the arrangement of the variates. Example (i). Consider the two series (a) 3 7 4 6 2 5 8 7 3 4 7 3 5 8 2 6 (b) 2 3 2 3 4 5 5 6 7 7 8 7 8 6 3 4
