Document Summary
Then, go back and confirm them generalize to different context discrete parts can"t be objectives. Research validity: often questioned because of lack of rigor & researcher bias, 2 strategies for reducing researcher bias: Reflexivity: thinking critically about one"s interpretations & Negative case sampling: searching for cases that challenge biases expectations or findings c) validity strategies that should be used: phenomenon data for a long period of time. Data triangulation: using multiple data sources to understand. Extended fieldwork: discovery & validation researchers collect. Low-inference descriptors: description phrased very close to participant"s accounts & researchers feild notes -> verbatims (direct quotes) phenomenon verification & insight. Methods triangulation: multiple research methods to study. Negative-case sampling: attempt to select cases that disconfirm. Participant feedback: researcher & participant"s feedback for. Pattern matching: determine if actual results fit the pattern or. Researcher-as-detective: careful of potential causes & effects, Theory triangulation: multiple explanations help interpret &
