presentation of data 2016-2017

Presentation of data in tables make them into a compact, concise and readily comprehensible form. They can display the characteristics of data more efficiently than the raw data.
1.Simple.
2.Understandable and self explanatory (all symbols should be explained in details in a foot note,each row or column should be labeled clearly, units of the data should be clearly mentioned,the title should be clear, precise, and should answer the questions, what? where? and when? and totals should be shown.
3.The title should be separated from the body
of the table by lines or spaces.
4.Avoid too much ruling.
5.If the data are not original,
their source should be mentioned
as a foot note or in the title.
The use of diagrams or pictures to describe the distribution or characteristics of one or more sets of data in a compact and readily comprehensible form. They can provide a better visual presentation
of characteristics of data than
tabular presentation.
1. Vertical and horizontal scales should be clearly labeled and units identified.
2. Keep graphs as simple as possible – avoid too many bars or lines – two or three is appropriate – more than four is probably too many.
3. Graphs are designed to provide a “snapshot” of the results – use tables for details.
4. Avoid presentation of numbers
in the body of a graph.
