A colleague is working on a text about a particular fungus disease due to wet grass. Tests have found different outcomes when removing dew from fairways at three different times of the day. A figure in the text says: Actual mean percent diseased area by mowing time for all disease assessment dates. Means with different letters are significantly different (LSD0.05) after means were log transformed to stabilize variance. Do you know what LSD 0.05 (subscript) means?
