Abstract

The next step in the research process would be summarizing the observations, and this forms the matter of discussion of Chapter 7, Describing Your Observations. Large number of observations seen in research studies need to be bunched together, and these are represented by summary values representative for the series. Two types of such summary values are commonly used in biomedical research; the averages and the dispersions, and we have covered how these are to be derived for grouped as well as ungrouped data series. Almost all the methods used for depicting dispersions have been discussed in brief, namely, variance, standard deviation, standard error, etc.
