This lot includes two vintage probability and statistics textbooks. The first one, 'Basic Concepts of Probability and Statistics,' is written by J. L. Hodges, Jr. and E. L. Lehmann, published by Holden - Day, Inc. in 1964. The second book, 'Nonparametric Statistics for the Behavioral Sciences,' is authored by Sidney Siegel and published by McGraw - Hill Book Company in 1956. The books are in acceptable condition. There is minor staining and soiling on the covers. The text blocks have darkened due to age and are soiled, but readability is not affected. There is light wear like minor rubbing on corners or spine ends. 'Nonparametric' has markings, underlinings from a previous owner, and a dried glue spot on the back pastedown. 'Basic Concepts' has a previous owner's stamp, minor staining on the front pastedown, and a detached pine from the text block, yet the pages are firmly bound. The bindings are tight and the pages are clean.
These textbooks are great resources for students or enthusiasts interested in probability and statistics. You can use them for self - study, classroom reference, or research. When handling these vintage books, be gentle to avoid further damage. To maintain them, store them in a dry and cool place away from direct sunlight. If you want to clean them, use a soft, dry cloth to gently wipe the covers. Do not use any harsh chemicals as they may damage the pages and covers. Also, be aware that due to their age, some of the pages may be brittle, so turn them carefully.
