With the existing of the data in the system and information technology, public health practitioner needs a clear understanding of the data analysis for measuring the performance and testing hypothesis related to the data obtained. In the practical world, everything has linked the graphics, statistics, and data and this analysis skill encourages the practitioner to dig deeper and ask more questions, improving their chance of making breakthrough discoveries in your data.

This skill of using the SPSS will let the researchers, making important discoveries of data analysis to a whole new level, letting the practitioner tackle routine and difficult statistical problems more easily and communicate your findings more effectively to the public domain and decision makers.
