- Can be customized for business needs.
Limitations of Primary Data
- Can be expensive.
- Requires more time.
- Needs trained researchers.
- Data collection may face low response rates.
- Analysis can be time-consuming.
Method 1: Surveys
Surveys are one of the most common methods of collecting primary data. They involve asking a group of respondents a series of structured questions.
Survey Formats
- Online surveys
- Email surveys
- Paper questionnaires

- Limited detailed feedback.
- Possibility of dishonest responses.
Method 2: Interviews
Interviews involve direct communication between the researcher and the respondent. Interviews allow researchers to gather detailed information and explore customer opinions in depth.
Types of Interviews
- Face-to-face interviews
- Telephone interviews
- Video interviews
- Online interviews
Advantages
- Detailed responses.
- Opportunity to ask follow-up questions.
