Hi there ,
Let’s discuss the collection of data for any purpose . There are two types of data collection methods 1. Primary data collection which the investigator himself collect for its own usages .and 2. Secondary Data which is collected by organisations for fulfilling their own purposes like Professional Bodies , surveys , reports and for various researches .
In Statistics data can be collected by various ways like
1. Directly interacting with the Groups of People .
2. the person can appoint local agents which are collecting the information and pack it up to Investigator or the person who requires the data
3. by oral conversation with third persons regarding the use of certain product which is producing .
4. via making scheduled visits to the concerned general respondent and ask him few questions & collect the data
5. the next is creating questionares and spreading it in various ways like personal interviews , emails , social media or other tele ways through which the data is collected .
The data is the Prime aspect of generating any reports and accurate measures must be taken to collect and arrange it .
