As you asking I am telling data collection is the process of gathering and measuring information on variables of interest, in an established systematic fashion that enables one to answer stated research questions, test hypotheses, and evaluate outcomes.

Qualitative research is a method of inquiry employed in many different academic disciplines, traditionally in the social sciences, but also in market research and further contexts.


Qualitative researchers aim to gather an in-depth understanding of human behavior and the reasons that govern such behavior.

Generally there are three types of data collection and they are

1. Surveys:
Standardized paper-and -pencil or phone questionnaires that ask predetermined questions.

2. Interviews:
Structured or unstructured one-on-one directed conversations with key individuals or leaders in a community.

3. Focus groups:
Structured interviews with small groups of like individuals using standardized questions, follow-up questions, and exploration of other topics that arise to better understand participants

Consequences from improperly collected data include:

Inability to answer research questions accurately.
Inability to repeat and validate the study.
