Table DOT1. t distribution

See nQuery Advisor® manual Appendix for computing method. Figure DOT1 shows t-values for 1 and 3000 degrees of freedom for probability .95. Additional values tested: Degrees of freedom 1, 2, 10, 30, 120, 10000 and probability .001, .005, .01, .5, .99, .995, .999 to t and those values of t back to probability. Values checked against tables in Dixon WJ, Massey FJ (1983) Introduction to Statistical Analysis. 4th edition. McGraw-Hill. New York and/or StaTable. Electronic Tables for Scientists and Engineers. Version 1. 1994 Cytel Software Corporation.
