why is different the information from survey to that from interview?
The information collected from surveys and interviews can differ due to several reasons:
1. Methodology: Surveys typically involve a structured set of questions that participants answer in a standardized format. This provides a large amount of quantitative data from a larger sample size. On the other hand, interviews are more open-ended and allow for in-depth discussions. Interviews provide qualitative data and allow for follow-up questions to gain deeper insights.
2. Participant Bias: In surveys, participants may interpret questions differently or provide socially desirable responses. They may also rush through the survey without giving thoughtful answers. In interviews, participants might feel more comfortable and open, allowing them to provide more detailed and candid responses.
3. Depth of Information: Surveys generally provide a broader overview of opinions or behaviors on a large scale, but they may lack the contextual details that interviews can provide. Interviews can delve deeper into individuals' experiences, thoughts, and emotions, providing a more comprehensive understanding of the topic.
4. Non-Verbal Cues: In interviews, non-verbal cues like facial expressions, body language, and tone of voice can provide additional insights that may not be captured in surveys. These cues can help understand a person's emotions, level of confidence, or hesitation related to certain topics.
5. Sample Selection: The samples in surveys and interviews may differ. Surveys often involve random sampling or reaching out to a broader audience, which can result in a more diverse sample. Interviews, on the other hand, may involve purposeful or convenience sampling, which can lead to a more specific or targeted group of participants. Different demographics or characteristics of the samples can impact the information collected.
It is important to consider these factors when analyzing and comparing information from surveys and interviews to understand the nuances and potential variations in the data collected.
