This paper derives a procedure for determining the expectations of order statistics associated with the standard normal distribution ( 𝑍 ) and its powers of order three and five ( 𝑍 3 and 𝑍 5 ). The procedure is demonstrated for sample sizes of 𝑛 ≀ 9 . It is shown that 𝑍 3 and 𝑍 5 have expectations of order statistics that are functions of the expectations for 𝑍 and can be expressed in terms of explicit elementary functions for sample sizes of 𝑛 ≀ 5 . For sample sizes of 𝑛 = 6 , 7 the expectations of the order statistics for 𝑍 , 𝑍 3 , and 𝑍 5 only require a single remainder term.
