PSY 3307 Lecture Notes - Lecture 4: Sampling Bias
Document Summary
Doesn"t cost as much as in-person interviews. Can get more qualitative information than written surveys. Biased sample (the types of people who actually answer phone interviews) People don"t like giving personal information over the phone. People could misrepresent themselves over the phone. Landline and phonebooks are becoming less common. With participants permission, you can record the interview. Can observe nonverbal responses and body language. Can ask more sensitive questions and build trust. If someone comes to you, it can be a disadvantage to them. Can"t always reach everyone (ie. rural areas) Takes more time to interview and analyze responses. You can complete the interview in your own time. Latency, might take time for survey to be mailed back. Not sure who is completing the survey. Not as accessible (lose people who cannot read or write) Only certain people will be bothered to respond. Takes time to input data into the computer.
