There are three types of rigour to consider. Procedural rigour, analytical rigour and overall rigour. With procedural rigour, consider whether the researcher has clearly described the procedures used (i.e. collecting the data) in the research. For analytical rigour, consider whether inductive approach was used for data analysis and their findings were logically consistent and reflective of the data. As for overall rigour, primary concept is trustworthiness of the evidence collected.
There are four components of the trustworthiness to consider while analyzing the evidence: credibility, transferability, dependability, and confirmability.
1. Credibility can show and support “true” picture of phenomenon or subject of what has been studied.

Confirmability will show and support strategies used to limit bias in the research. This can be done by researcher’s reflection, journal, peer review by colleagues, peer review by expert, and peer review by participants.
When you compare the methodological rigor of quantitative research. Quantitative research discusses concepts such as validity, reliability, and applicability. Qualitative research uses above terminology to determining the trustworthiness of the research.
• Identify one issue surrounding the evaluation of a qualitative study (e.g. type of qualitative study chosen, data collection procedures, ethical considerations, sampling strategy, data analysis techniques, disclosing researcher bias/role in research or etc.) which could lead to an erroneous conclusion about the trustworthiness of a qualitative study.
One disadvantage that can possibly present by using qualitative method as focus groups. Researcher must ensure that all participants have an opportunity to voice their opinions and be heard within the group. Assigned facilitator of the focus group must be skilled in group process and interviewing techniques. Without ensuring all participants opinions, research can possibly lose rigour in credibility and confirmability and will lead to erroneous conclusion about trustworthiness of a
