Research Methods: Biases in Research - Sample Selection Bias

I think we are slowly approximating the end of the topic of biases. No, please do not think, the biases are over - a friend and colleague of mine Professor Ganna Pogrebna wrote a book on biases in research and, believe me, there are many more. So feel free to google this book or write in comments if you haven't managed to find it. In this podcast, I mentioned only the main biases I encountered during my research. 

Today, we talk about sample selection bias. It is dangerous in research but even more dangerous is this bias in politics when election polls are conducted. Listen carefully and try to avoid this bias in your research.

Good luck!
