This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1911 Excerpt: ...and the equations of regression for the following values of X and Y. X. Y. 1 2 2 5 3 3 4 8 5 7 As a matter of practice it is never worth calculating a correlation-coefficient for so few observations: the figures are given solely as a short example on which the student can test his knowledge of the work. 2. The following figures show, for the districts of Example i., the ratios of the numbers of paupers in receipt of outdoor relief to the numbers in receipt of relief in the workhouse. Find the correlations between the out-relief ratio and (1) the estimated earnings of agricultural labourers; (2) the percentage of the population in receipt of relief. 3. Verify the following data for the under-mentioned tables of the preceding chapter. Calculate the means of rows and columns and draw diagrams showing the lines of regression, as figs. 36-39, for one or two cases at least. In calculating the coefficient of contingency (coefficient of mean square contingency) use the fullowing groupings, so as to avoid small scattered frequencies at the extremities of the tables and also excessive arithmetic: --I. Group together (1) two top rows, (2) three bottom rows, (3) two first columns, (4) four last columns, leaving centre of table as it stands. II. Regroup by ten-year intervals (15-, 25-, 35-, etc.) for both husband and wife, making the last group "65 and over." III. Regroup by 2-inch intervals, 58'5-60"5, etc., for father, 59"5-61'5, etc., for son. If a 3-inch grouping be used (58-5-61'5, etc., for both father and son), the coefficient of mean square contingency is 0'465. Both results cited from Pearson, ref. 1 of Chap. V. IV. For cols., group 1 + 2, 3 + 4, ..., 11 + 12, 13 and upwards. Rows, 0,1 + 2,3 + 4, ..., 9 +10, 11 and upwards., CHAPTER X. CORRELAT...
