William John Youden (April 12, 1900 – March 31, 1971) was a statistician who formulated new statistical techniques in statistical analysis and in designs for experimenters. He developed the "Youden square", an incomplete block design developed from a 1937 paper, "Use of Incomplete Block Replications in Estimating Tobacco Mosaic Virus". He also helped to introduce the concept of restricted randomization, which he called constrained randomization.[1][2][3][4]

The American Statistical Association bestows the W. J. Youden Award in Interlaboratory Testing to authors "of publications that make outstanding contributions to the design and/or analysis of interlaboratory tests or describe ingenious approaches to the planning and evaluation of data from such tests." The award is presented each year at the Joint Statistical Meetings.[5]
