G.C.E O/L Information and Communication Technology 2 - New Syllabus

Tutorial 02: Information and Communication Technology 

Let's find out more about data vs information. Example 1: Here I mentioned results of three student in last term test following with their names and marks. 

Bill: 65, 91, 57, 96. Rizm: 64, 84, 49, 93 and Curli: 91, 59, 72, 89. Actually, if we write names and marks separately, it will be difficult to get an idea about the subject and marks and who is the best student as well.

But these names and marks can be tabulated as follows. 

Name	Maths	English	Science	ICT
Bill	65	91	57	96
Rizm	64	84	49	93
Curli	91	59	72	89

Above table shows students and their marks in a good readable format. However, these details may not be sufficient to get some meaningful conclusion. This tabulated marks can be subjected to calculation as follows. 

Name	Maths	English	Science	ICT	Avg.	Rank
Bill	65	91	57	96	77.25	2
Rizm	64	84	49	93	72.5	3
Curli	91	59	72	89	77.75	1

Now, you can see clearly teacher can be able to get the required information using this table to select the best student (the total score of each student, their average score, individual skill of each student per subject and the rank). Thus teacher can take important decisions by information which was tabulated as above.
