Researchers such as Silverman (2015) have explained how researchers in qualitative research can combine measures that mostly deal with qualitative research. 4.3 QUANTITATIVE ANALYSIS In order to achieve the empirical objective of the research, the results were analysed and presented as they appear in the different sections of the questionnaire (refer to Appendix B). 6. Ecological validity, an aspect of external validity, refers to whether a study's findings can be generalized to the real world. However, since it cannot be quantified, the question on its correctness is critical. In this case, “other contexts” can mean similar situations, similar populations, and similar phenomena.

Meticulous attention to these two aspects can make the difference between good research and poor research and can help to assure that fellow scientists accept findings as credible and trustworthy. Qualitative data is as important as quantitative data, as it also helps in establishing key research points. Validity and reliability of observation and data collection in biographical research Summary The role of biographical research in the medical and health sciences has often been criticized. Trustworthiness of qualitative research, most of the time is questioned by positivists reason being that validity and reliability is not addressed like how it is done in naturalistic work. Internal validity is the extent to which a study establishes a trustworthy cause-and-effect relationship between a treatment and an outcome.1 It also reflects that a given study makes it possible to eliminate alternative explanations for a finding. (2011). Validity is one of the main concerns with research. Summary of Findings In quantitative research: Summary of the Findings In qualitative research: Summary of Results Summary of Findings Must directly answer sub-statements of the problem.
