How is data organised?
Let us understand the organisation of data with the helo of an example. Given below is the marks obtained by students in an English exam:
23, 35, 48, 30, 25, 46, 13, 27, 32, 38
To organise this data, it can be tabulated in the following manner: This helps in a better understanding of the given data.
| Roll numbe r | Student name | Marks obtained out of 50 |
| 1 | Ajay | 23 |
| 2 | Armaan | 35 |
| 3 | Ashish | 48 |
| 4 | Dipti | 30 |
| 5 | Faizaan | 25 |
| 6 | Govind | 46 |
| 7 | Jay | 13 |
| 8 | Kavita | 27 |
| 9 | Manisha | 32 |
| 10 | Neeraj | 38 |
Let us now see how this table can be used.
For example,
If the top 3 and bottom 3 scorers in the English exam have to be identified, arranging the data in descending order of the marks will give the information
| Roll numbe r | Student name | Marks obtained out of 50 | |
| 3 | Ashish | 48 |
Top 3 scorers |
| 6 | Govind | 46 | |
| 10 | Neeraj | 38 | |
| 2 | Armaan | 35 | |
| 9 | Manisha | 32 | |
| 4 | Dipti | 30 | |
| 8 | Kavita | 27 | |
| 5 | Faizaan | 25 |
Bottom 3 scorers |
| 1 | Ajay | 23 | |
| 7 | Jay | 13 |
Some examples of data that is arranged in tabular forms include school rolls, progress report, index in the textbooks and so on.
