Abstract
Statistical science plays a major role in any scientific
investigation. The use of appropriate statistical techniques
for analysing data is very crucial to obtain a meaningful
interpretation of the investigation. Statistical analyses play
an important role in agro-meteorology, as they provide a
means of interrelating series of data from diverse sources,
