An observer who will not take any part in the study environment is called a Passive Observer.

Open$-$ended or unstructured interviews are exploratory.

Suppose you want to do a study to collect data, and you have two groups of potential participants: G$1$ and G$2,$ where G$1$ was involved in the pilot study. In that case, involving G$2$ in the main study is better than involving G$1.$

Unstructured interviews mean that there is no plan for the interview.

In unstructured interviews, the same set of predetermined questions are asked for all participants.

The between$-$subject experimental design lessens the impact of individual differences.

The within$-$subject design usually requires a larger number of participants.
