How are selection bias and design bias different?

Selection bias would be for example, when a researcher decides to ask VOLUNTEERS to participate in a study...mostly will be students who need the money and therefore it would not represent the actual population and you would have selection bias.

Study design is basically having flaws in the study experiment that generate bias. For example, not having a randomized sample will generate selection bias Happy-2

Not exactly. Students would represent healthy people mostly and are a good cohort for phase I clinical trial.
