ABSTRACT

One of the major objectives of science is to estimate value of one variable by reference to the value of an associated variable. According to Karl Pearson, the scientific method consists in the careful and laborious classification of facts, the comparison of their relationship and sequences and finally in the discovery by the aid of disciplined imagination of a brief statement or formular, which in a few words resumes a wide range of facts. Such a brief statement is termed a scientific method. Karl Pearson further gave a summary of what a scientific research method should look like. Simply put, he said that scientific research method is a conscientious research process that consists of the classification and comparison of the relationship of observed variables that would culminate in the establishment of a scientific law that portends a wide range of facts. (Applied general statistics by Fredrick E. Colton et Child bearin is regarded as a vital and necessary activity in the world today, this is why people come together for marriage not only to live together but also to produce a generation of children. Thus, to maintain a continuum in any generation, new beings must be born. When a woman conceives, she visits the hospitals, clinics or maternity for ante-natal care. At the expiration of nine months or more, she gives birth to a new human being. Before delivry, the mother's blood pressure (B.P), Haemoglobin (H.b) level, weight e.t.c. are checked to see if she can really cope up with the stresses of labour. After birth, in the hospital
