Characteristics of Information Sources

Often times people debate about the quality of information because of where it comes from. For example, if I should say to you that the STAR or the X-NEWS reported that some DJ artist was in some disagreement then one could argue whether it is true or just a plot to sell paper. If the Gleaner however, report that same information then the possibility is that the information is more truth than the STAR or the X-NEWS.

Why one would be more likely to believe the Gleaner over the STAR or the X-NEWS is because of the credibility of the papers. The degree of confidence you have will ultimately determine whether you use information from that source in decision making. The following are some of the characteristics of information sources:

1. scope – depth and breath of  the information in the source
2. content – information contained in the source
3. accuracy- truthfulness of the information
4. purpose – stated reasons for maintaining information in the source and the intended users
5. authority – maintenance of the source by reputable persons or organizations who possess expert knowledge in the area
6. currency – timeliness of truthful information
7. reliability – consistency with which information is correct
8. audience – group of persons for whom the information is presented
9. format – the manner in which information is presented
10. availability – to access the available information when and where needed
11. medium- whether or not information is provided in text, audio or video
12. cost – expenditure outlaid to access or make the information available.
13. depth of coverage - amount of detailed (detail – number of features revealed by the source)
14. breadth of coverage -  This defines the scope of information

NB: There is  a textbook that can help you in the two years....have it softcopy... it is a big file you will have to bring memory stick next class to get it cuz too big to upload.
