A researcher using methodology is most likely to use objectivity (as opposed to strong objectivity).

Mostly the researchers use qualitative methodology to investigate the objectivity.

Explanation:

There are mainly two methodologies use for research.

Qualitative research methodology:

It is also known as exploratory research because in this type of research we explore the subject reasons, motivations, and opinions to generate new hypothesis or ideas for qualitative research. In this research, the sample size is small and main focus on interviews, surveys, and group discussion.

Quantitative research methodology:

As this is known through the name, in this methodology we use the data in statistical form to explore the problems or to quantify the problems. The sample size is more than qualitative research.
