PROBLEM SOLVING ON COMPARISON OF TREATMENT MEANS BY
LSD TEST. (Show all solutions)

1. Using the obtained Mean Yield in kg/ha( Column 2) Compute the Mean
difference between the CONTROL treatment and each of the 10 treatments
and fill up COLUMN 3.

2. Compute the LSD Value at a level of significance

FORMULA LSD (.O5) = Tabular f(.05) 2EMS

r

LSD (.O1) = Tabular f(.01) 2EMS

r
given: EMS = 94,773, ERROR DF = 21, NUMBER OF REPLICATION = 4.

TABULAR F VALUES 5% LEVEL = 2.O8 , 1% LEVEL = 2.831.
