Abstract
Examination of yield data of coconut for individual years revealed that the distribution is always positively skewed and leptokurtic. Pooling the data for consecutive years as well as consideration of palms in groups did not improve the distribution. Among the different transformations tried, Vx X 10 transformation was found to bring the data to a near normal distribution in most cases. Another difficulty experienced while analysing the yield data of coconut experiments is the large error variance. With pooling of data for consecutive years, variance was found to get reduced. Covariance analysis was found to result in increased efficiency.
