摘要:

Estimates of money and real earnings of nonfarm employees are presented for the years 1890 to 1946, these estimates reflecting the loss in earnings which arises from unemployment. Series are likewise given for full time equivalent earnings of nonfarm employees as a group and for each of the major industry groups for 1919–46, while the Bureau of Labor Statistics and the Bureau of the Census have developed estimates of unemployment for the period 1920–46. The sources of the rise in earnings after World War I are analyzed and it is concluded that about three-fourths of the rise in earnings derived from increased pay on a given job, while one-quarter originated in the changing distribution and characteristics of nonfarm employees.

This note presents a chart which can be used by draftsmen to determine directly from raw area data compass settings for plotting proportionate area circles without any of the usual square-root and proportioning computations.

摘要:

This article is concerned with certain graphical devices, called “Profile Graphs,” for the integrated presentation of data of several dimensions. The several types of such profiles (two-and three-dimensional, simple and composite, statistical and historical) are explained; their advantages and disadvantages discussed; and illustrations given for the several types.

摘要:

The standard method of dealing with sensitivity of dosage-mortality data is the probit technique developed by Bliss and Fisher. This paper provides an alternative technique based on a special system for obtaining such data. It has some advantages when observations must be taken on individuals rather than groups of individuals, and it may be preferred in certain other situations.

摘要:

“Growth” curves have been used in many fields despite the extensive calculations required. These curves may be applied even more widely if their construction can be simplified. This article shows how to fit a logistic (Pearl-Reed) curve quite simply by means of a nomograph (which determines the upper limit from three selected points) and a logistic grid (which reduces the curve itself to a straight line).1Other “growth” curves may be fitted by constructing appropriate graphs.
