Chapter 9: What are the major methods of Data Collection?
Fundamental Principle of mixed research: To get high quality research, there must be thoughtful mixing of methods, procedures, & other paradigm characteristics
include types of mixing
intramethod mixing
is
both quantitative & qualitative data are obtained through one method
mixing of other research ingredients
is
sampling methods & data analysis methods
Intermethod mixing
is
2 or more methods of data collection are used
Questionnaires
used
to self-report data tool as part of a study; used to obtain information about thoughts, feelings, attitudes, beliefs, values, etc.
Tests
used
to measure attitudes, personality, self-perceptions, aptitude, & performance of research participants; quantitative research
Focus groups
are
group interview where moderator leads discussion with small group of individuals to examine how they feel about a topic
qualitative data collectors
composed of 6-12 participants
Interviews
occurs
between interviewer and interviewee
Quantitative interviews
consist of
interview protocol that includes the items, response categories, instructions, etc.

is
structured; involves standardization of each
When the observation takes place
What is observed
Where the observation takes place
Who is observed

Results are counts, frequencies, or percentages
Techniques
Time-interval sampling
Event sampling
Qualitative observation
is
observing all potentially relevant phenomena & taking extensive field notes
Participant as observer
Observer-as-participant
Complete participant
Complete observer
Constructed, Secondary, or Existing Data
Constructed data - constructed by research participants; drawings, diaries, recordings, etc.

Documents
personal documents - anything written, photographed, or recorded for private purposes
Official documents - written, photographed, or recorded by some type of public or private organization
Physical data - any physical trace left by people as they take part in activities
Archived research data - originally used for research purposes an then stored for potential use later
