Produktbeschreibung
Excerpt from City School Expenditures: The Variability and Interrelation of the Principal Items The importance of the subject-matter of Mr. Strayer´s investigation needs no comment. The methods, being in some respects new in the literature of education, deserve some comment. It is impossible to gain adequate insight into facts as complex as those of school expenses and school achievements without some use of technical statistical methods. If Mr. Strayer´s report puzzles some readers by its tables of frequency, its constant use of the median rather than the average as a measure of central tendency, its coefficients of correlation and their corrections, it is of necessity. The facts could not otherwise be handled properly - in some cases not at all. The one matter of technique which needs explanation and perhaps apology is the use of the Pearson Coefficient of Correlation. This measure of the general relation of a deviation of the amount of one item in the budget from the typical amount of that item to the deviation in the same city of some other item from its typical amount, is indispensable but necessarily obscure.
