we conclude that the purpose for which a data is to be collected has to be kept in mind before starting the process of data collection.

**Collection of data**

We need to collect data having the specific
information in our mind. Suppose the specific information needed by us is to know
the height of class VII students, then we should collect specific data related to
their heights and ages rather than the data related to health record of students.

From the above discussion, we conclude
that the purpose for which a data is to be collected has to be kept in mind before
starting the process of data collection. Then only we can get the desired information,
which is appropriate to the purpose. Let us look into a few situations that are
given below.

Data can be generated in many situations
around us. For example,

● The height of class VII students.

● The performance of class VII students
in the term II examinations.

● The number of trees planted in your
locality.

● The highest temperatures recorded in
all the major cities of India during the year 2018.

● The least amount of rainfall recorded
in all the districts of Tamil Nadu during the year 2018.
