Question

In which of the following cases is direct personal observation method adopted?
A. Where greater accuracy is needed
B. When the field is a complex one
C. When intensive study is needed
D. All of the above.

Answer 1

Hint: In this problem, we have to find in which of the following cases is direct personal observation method adopted from the given options. We should know that direct personal observation methods are adopted when intensive study is needed. We can now see it briefly.

Complete step by step answer:
Here we have to find in which of the following cases is direct personal observation method adopted from the given options.
We should know that direct personal observation methods are adopted when intensive study is needed.
We know that direct personal observation is the method adopted so that an intensive study of the population can be done. Direct observation helps in getting accurate results as their behaviour can be easily ascertained.
It is the data collected by the investigator personally.
It is also adopted in the cases such as, where greater accuracy is needed, where the field of enquiry is not large, where confidential data are to be collected and where sufficient time is available.

So, the correct answer is “Option C”.

Note: We should also remember some of the cases which are adopted are where greater accuracy is needed, where the field of enquiry is not large, where confidential data are to be collected and where sufficient time is available. Direct observation helps in getting accurate results as their behaviour can be easily ascertained.
