Construction Measurements

Errors in Practical Measurement in Science, Engineering, and Technology B. Austin Barry A step-by-step presentation of how random errors occur when taking measurements, how these errors behave, how measurement errors can be used to determine the reliability of the values, and how to accord weights to different measurements of the same quantity. Introduces the concept of percentage compliance with a demand specification, discusses practical plotting of frequency distribution curves, offers tables of areas beneath the normal curve to assist in formulating the validity of measurements, and provides basic information of the probability ellipse for two-dimensional errors. Appendices contain a review and reference of significant figures, complete information for writing a specification for a procedure, suggestions for the use of a Fortran program, and more. 1978 (0 471-03156-9) 183 pp.
