Book Description

Measurements, sampling and data analysis remain a very crucial if not the fulcrum of research activities. There is not research study for which measurement and analysis are not done. For every research study to be undertaken, the researcher must have a concept for which he or she needs to find a way of measuring. However, concepts are vague ideas and thus must be reduced to variables for them to be measured. It is thus only variables that can be measured for data to be collected as empirical evidence to support a research study being conducted.

It is a complete book with several book chapters vital to understanding research through measurements, sampling and its techniques, data transformation and data analysis in a practical and comprehensive way. The book is intended to equipped lecturers, researchers, tertiary students and all those interested in researches with the appropriate skills and know-how in the conduct and appreciation herculean tasks of a researcher. It would be of immense benefit to final year tertiary students conducting their research and writing of their research reports.
