Focus groups is type of group interview designed to explore peoples attitudes. It can be used to find out what issues  are of most concern for a community or group when little or no information is  available. They are a very common technique but are can be poorly executed unless well planned and facilitated.

The girl who loved the Oceanario by Pedro Moura Pinheiro
The fish bowl activity is used to manage group discussion. The general idea is that rather than a large group having an open discussion about something, which can be difficult to handle and often only benefits a few active participants, a smaller group (ideally 3 – 6 people) is isolated to discuss while the rest of the participants (maximum of 50 people) sit around the outside and observe without interrupting. Facilitation is focused on the core group discussion. Less people = easier to facilitate.

Computer science mindmap by Till Tantau
A concept map shows how different ideas relate to each other - sometimes this is called a mind map or a cluster map. This option can be used for the task of negotiating values and standards, and is useful for framing the evaluation. Concept Mapping can be used before, during or after implementation of a project/program/policy. It is necessarily done in a group and it requires sufficient time (the group needs to provide input individually and then meet) and specialist software.

In many research contexts, sampling simply involves asking for volunteers. Although this can be a convenient, quick and inexpensive way of sampling, the problem with basing a study on a group of volunteers is that there is no evidence that this sample is representative of the wider population that the researcher would like to make generalizations about.
