How Do You Find Groups To Fill Research Questionnaires?

You may know what sort of research you are doing. Then keep searching for relevant groups. This can be possible by targeting that audience which is relevant to your research work. For instance, if you are doing a research on the topic of industrialization and you are distributing questionnaires among students then it is totally wrong on your behalf. You must distribute these questionnaires among those who are concerned with industrialization. In this way, you would be able to get relevant data.
Always try to avoid biased data. Biased data comes up when you don't work in a right direction. In this way you fail to get what you are seeking for. So, it is a negative thing on your behalf. Try to hit the group which knows more about what you are doing. They must know that what you are seeking for. Appreciate their comments too. This would be helpful to your work in many regards. Group selection can be done after proper discussion with relevant people. You should do it yourself.
