Learn moreWe learned that data is a compilations of information, but there are two ways we can classify the data with respect to the way it gets collected.
Data types:
1. Primary data.
2. Secondary data.
Primary data: A data which has just been freshly collected from original source and not treated with statistical process such as tabulating and sorting.
Example:
1. The agricultural students have collected the variety of plant samples in the agriculture field.
2. The media collected the information from the people about their favourite political leader.
3. A teacher collected a list of absentees in the class.
4. A survey on eating habits of students conducted by a food manufacturing company.
Secondary data: For some other purposes, if someone collects second-hand data, that set of information is called secondary data. And this is not collected directly from the source.
Example:
1. The local news channels collects the data from the international news channel.
2. The headmaster of the school collects the data about school toppers from all the class teachers.
