Garret’s ranking technique
The questionnaires issued to the farmers provided significant information regarding sugarcane farming in Khyber Pakhtunkhwa. The opinions of such farmers were analyzed through the use of the Garret’s ranking technique. The ranking approach was used in assigning the opinions of the farmers’ statistical values. The percentage position as assessed through this formula is
100*(RIJ-0.5)/N
Rij is the rank assigned to the ithconstraint by jth individual. On the other hand, Nj is the number assigned to constraints identified by the jth individual. The estimation of percentages then led to the conversion of such percentages to the numbers through the use of the Garret table. The constraint that had the highest mean was taken to be the one that had the greatest impact on the phenomena under study.
