Answer 1

Research in public health is mainly governed by the statistics without which result formation of the research will not be possible. For the study to be conducted, the main thing that is required is a study population. The same thing is study sample. The term population means a group of people living in a specific geographical location. But for the study to be conducted ,the entire population cannot be selected. So we will select people from a particular population randomly so that the group of people will represent the entire population. Such group of people can be called as study sample.

The statistical data involved in any research program are, data collection, data analysis, finding correlation coefficient, standard deviation, variance, p value. By calculating any of this, depending on the study type, we can reach at the conclusion.
