Steps of Data Collection, cont'd

In addition to the general considerations for each step of the data collection process, the five qualitative approaches have specific considerations and issues to consider prior to beginning data collection.

Locating Site/Individual Single individual; accessible and distinctive
Issues with gaining access and building rapport Gaining permission from individual(s), obtaining access to information in archives
Purposefully sampling Depends on the person (may be convenient, politically important, typical, unusual, etc.)
Collecting data In-depth interviews; also document and archival analysis, journaling, observation
Recording Notes, interview protocol
Data storage File folders, computer files
Data collection activity: Phenomenology
Locating Site/Individual Multiple individuals; all must have experienced the phenomenon of interest
Issues with gaining access and building rapport Finding individuals who have experienced the phenomenon
Purposefully sampling “Criterion” sample
Collecting data In-depth interviews
Recording Interview protocol(s), often multiple interviews with the same individuals
Data storage Transcriptions, computer files
Data collection activity: Grounded Theory
Locating Site/Individual Multiple individuals
Issues with gaining access and building rapport Locating a homogeneous sample
Purposefully sampling “Theory-based” sample
Collecting data Primarily interviews (in-depth interviews and focus groups)
Recording Interview protocol, memoing
Data storage Transcriptions, computer files
Data collection activity: Ethnography
Locating Site/Individual Members of a culture-sharing group or individuals representative of the group
Issues with gaining access and building rapport Gaining access through the gatekeeper, gaining the confidence of informants
Purposefully sampling Finding a cultural group to which one is a “stranger”
Collecting data Participant observations; also interviews, document archival analysis, and artifacts review
Recording Fieldnotes, interview and observational protocols
Data storage Fieldnotes, transcriptions, computer files
Data collection activity: Case Study
Locating Site/Individual A bounded system (can be a person or people, a process, an activity, an event, a program)
Issues with gaining access and building rapport Gaining access through the gatekeeper, gaining the confidence of participants
Purposefully sampling Finding a “case” or “cases”
Collecting data Extensive forms—documents and records, interviews, observation, and artifacts
Recording Fieldnotes, interview and observational protocols
Data storage Fieldnotes, transcriptions, computer files
