Exploratory research is "the preliminary research to clarify the exact nature of the problem to be solved." It is used to ensure additional research is taken into consideration during an experiment as well as determining research priorities, collecting data and honing in on certain subjects which may be difficult to take note of without exploratory research.
The use of novel human survey distribution methods has a significant impact on research outcomes. A study demonstrates the effectiveness of innovative strategies such as QR-coded posters and targeted email campaigns in boosting survey participation among healthcare professionals involved in antibiotics research.

In the statistical theory of design of experiments, randomization involves randomly allocating the experimental units across the treatment groups.For example, if an experiment compares a new drug against a standard drug, then the patients should be allocated to either the new drug or to the standard drug control using randomization.
In contrast to standardized research methods, recursivity embodies the idea that the qualitative researcher can change a study's design during the data collection phase. [12] Recursivity in qualitative research procedures contrasts to the methods used by scientists who conduct experiments. From the perspective of the scientist, data collection ...
Garfinkel expanded on this idea by developing ethnomethodology as a qualitative research method for social scientists. Later, in the 1970s and 80s, famous social psychologist Stanley Milgram developed two experiments to observe and quantify responses to breaches in social norms to empirically analyze reactions to violation of those norms.
In qualitative research, a member check, also known as informant feedback or respondent validation, is a technique used by researchers to help improve the accuracy, credibility, validity, and transferability (also known as applicability, internal validity, [1] or fittingness) of a study. [2]
