Konteks lain juga boleh dalam keadaan yang sama, populasi yang sama dan fenomena yang serupa
Credibility can be achieved by: 1)prolonged engagement with participicant 2) persistent observation in the field 3) the use of peer debriefers/peer researcher 4) triangulation 5) referential adequacy 6) member checks
kesahan muka boleh mempengaruhi, orang tidak akan menjawab dengan serius.
Konteks lain mungkin dalam keadaan, populasi, situasi dan fenomena yang berbeza
thinking about different generalizability contexts and developing a theory about which contexts are more like our study and which are less so :

When the subject develop or change during the experiment as part of an ongoing process independent of the experimental treatment
sampling model
start by identifying the population you would like to generalize to
click to edit
draw a fair sample from that population and conduct your research with the sample.
automatically generalize your results back to the population
imagine several settings that have people who are more similar to the people in our study or people who are less similar.
Evaluation of the quality of the integrated processes of data collection , data analysis and theory integration
