List the method of collecting primary data?

Hint: As this question is not a numerically based question, so will be more focusing on the theory of basics of statistics. So, we will see what data in statistics is and what types of statistics are. Then, we will see what different modes of collecting primary data are.

Complete step-by-step solution:
Basically, in statistics, there are basically two types of data, namely primary data and secondary data. Both data helps in doing research and collecting information, but the main difference is the source of the collection of information.
Now, in statistics, data basically are the individual pieces of factual information recorded and used for the purpose of analysis or research. It is the raw information, which statistics are created. Statistics are the result of data analysis by doing interpretation or presentation. Also, these types of statistics are referred to as ‘statistical data’.
In statistics, primary data is data that is collected by the researcher from first-hand sources using methods like surveys, interviews, or experiments. It is collected with the research project in mind, directly from the primary sources. Ere first-hand sources mean the original documents such as manuscripts, interviews, records, eyewitness, etc.
So, examples of primary data are raw data, original research, journal, articles, books, etc.

Note: It is not necessary that there will always be numerical questions in statistics, the weightage of theoretical concepts matters a lot. So, one must clear all concepts which are associated with subject statistics. Even knowing only definition and some examples help in giving the hint and solving the question.
