Abstract
The percentage point values of the Student's t-distribution were calculated with a Sharp PC-1211 calculator down to the fourth decimal place.
When the data were compared with those in the Fisher and Yates' t-table (1949), five errors were found in the latter: for 31. 598 (D. F.=2, P=0.001) read 31. 599; for 12. 941 (D. F.=3, P=0.001) read 12.924; for 6.859 (D. F.=5, P=0.001) read 6.869; for 5.405 (D. F.=7, P=0.001) read 5.408 and for 3.767 (D. F.=23, P=0.001) read 3.768. Although three of the errors were corrected in the 1963 edition, two erroneous values, 31. 598 and 3.767 remained.
The author found that most textbooks for statistics quoted the original table, except for those written by Yamauti et al. (1972) and Kuebler et al. (1976). Such errors in quotation obviously need to be corrected.
