1.7 LIMITATION OF THE STUDY
A lot of factors militated against this project work. The most inflicting problem was time. As a student caring out the study with my ministerial and other domestic callings, the time schedule for this study seems inadequate.
Another major constraints includes lack of data and willingness of the custodians of those data from the nation to make it available for at least photocopy. Even the material in the libraries are grossly out data easy to come by funds needed for this research was enormous at least to cover transportation and photocopy of materials and this is earnest affected and determined the scope of this study.
All these constrains, notwithstanding with God’s guidance and provisions coupled with the corporation of my superior in higher learning, the study was successfully complete and within time scheduled.
