उत्तर
The presentation of the data in a tabular form helps in quickly grasping and analyzing the recorded observations. For example, to measure a diameter using a vernier caliper we record the following data in a tabular form as follows
Vernier caliper
| No. of observations | Main scale reading (cm) | No. of vernier divisions p coinciding with main scale | Vernier reading =L.C. X p (cm) | Observed diameter |
| 1 | ||||
| 2 | ||||

The measurements corresponding to one physical quantity from one instrument must be recorded in one table. And the name of the instrument should be written on top. Observation must be recorded up to the limit of the instrument and form the recorded individual observations, calculate the mean value, and record it at the bottom of the column.
