Abstract

In the fieldof weed science,data transformation techniques are of frequent use while evaluating investigating weed count data. Even after having its criticism, data transformation still remains as a very popular technique because the reasons for its use are quite greater than its non-use. Depending on the functional relationship existing between mean and variance of the weed count data, suitable transformations like logarithmic, square root and angular, should be used.
