请问在SAS的统计结果中，拥有共同的字母就代表差异不显著，拥有不同字母差异显著，那么如何看及显著呢？
比如：The ANOVA Procedure
                                    t Tests (LSD) for a

                           Error Mean Square          0.000289
                           Critical Value of t          2.10092
                           Least Significant Difference 0.0292
                  Means with the same letter are not significantly different.

                              E    0.48953    3 jc01
可以认为相隔字母就是差异及显著吗？
