- 15 KEY ISSUES in collecting user data1. Setting a Goal
2. Identifying Participants
3. Relationship with Participants
4.Triangulation
5. Pilot Studies - 2How does setting a goal affect your data collection process?1. Affects the nature and the number of data gathering sessions
2. Affects the data gathering method you will choose
3. Affects how you will be analyzing the data - 3Identifying Participants - What is a population?The type of participants that fit into your criteria, defined by the goal you have set for your studies.
- 4SamplingChoosing the participants to include in your data gathering.
- 5Saturation SamplingHaving access to all members of your target population.
- 6Probability SamplingIn this case, you are able to make generalizations about your population based on the data you've analyzed, by using statistical tests.
- 7Non-Probability SamplingIn this case, the data you've gathered doesn't allow you to make robust generalizations about your population.
- 8Random SamplingApproach used in PROBABILITY sampling - by using random number generator - choosing every nth person on the list.
- 9Stratified SamplingUsed in PROBABILITY sampling - dividing a population into groups and applying random sampling.
- 10Convenience SamplingUsed in NON-PROBABILITY sampling- working with participants who are available, RATHER THAN selected
- 11Volunteer PanelsUsed in NON-PROBABILITY sampling-
participants being prepared to take part. - 12What can be done to strengthen the relationship between participants and data collectors?1. Informed Consent Form
2. Incentives (especially for questionnaires) - 13What should an Informed Consent Form include?Making sure participants know and are happy about: how data will be gathered and used. Also that they can withdraw anytime they like.
- 14What's TRIANGULATION?Using at least two different perspectives in a study to for examining the quality of results.
- 15What are the FOUR TYPES OF TRIANGULATION?1- Triangulation of Data
2- Investigator Triangulation
3 - Triangulation of Theories
4 - Methodological Triangulation - 16What is a PILOT STUDY?Running a small trial of your main study to make sure it's working as expected.
- 17What are the advantages of DIRECT OBSERVATION?1. Actually observe users carrying out an activity
2. Finding out WHAT users really do, rather than what they SAY they do
3. Yielding detailed information when tasks are hard to verbalize - 18What Observer Participation levels are there?1. Total Outsider absolutely no interference
2. Insider: observer who also participates
OR
1. Marginal: interferes in small ways
2. Complete: "going native" but maintaining professional distance - 19What is ETHNOGRAPHY?Writing about people, immersing oneself into the culture and customs of target population. Marginal/complete participation is referred to as "ethnography"
- 20What are some basic steps in OBSERVATION?1.have a clear purpose
2.decide on a framework for data collection
3.decide on how to gather data (notes/photos/video??)
4. how to gain access & ethics
5. capturing DETAILS are important
6. try to keep away bias
7.consider teamwork & compare results - 21Describe the basic framework for observation?Observe:
The person. WHO?
The place. WHERE?
The thing. WHAT? - 22What are some strengths of observation?1. yield info on activities that have observable behaviour or stages
2. Detailed, in-depth info
3. good for activities with many individual steps that are difficult to describe verbally
4. revealing info about unexpected or unknown activities - 23What are some drawbacks of observation?1. may involve personal bias on the recorder's side
2. if the activity is cognitive than physical, not really useful
3. shouldn't be used as the only data gathering method
4. time-consuming - 24What should interview/questionnaire queries aim to address?1. FACTS - what people know
2. BEHAVIOUR - what people do
3. BELIEFS / ATTITUDES - what they think or feel - 25Define open questions.No restrictions on response. They rely on free RECALL.
- 26Define closed questions.Respondents may choose an answer from available, pre-determined alternatives. They rely on RECOGNITION of available answers.
- 27Define scale questions.Respondents must provide a rating as an answer, which is presented to them on a scale.
- 28When is... -an interview/ -a questionnaire most useful?Interview is more useful, with open-ended questions early in the design process. Closed questions & questionnaires are more useful during evaluation phase.
- 29Pros and cons of OPEN QUESTIONS?PROS:
- useful in early design to obtain unanticipated and general information
CONS:
- hard to analyze data from open questions - 30Pros and cons of CLOSED QUESTIONS?PROS:
-very useful in evaluation/later stages of design
-easier to analyze data from closed questions
CONS:
-require certainty regarding range of possible answers
-they are inflexible - 31What are the STRENGTHS of Interviews and Questionnaires?1. Faster than observations
2. You can cover things that can't be observed
3. You can cover infrequent happenings - 32What are the DRAWBACKS of Interviews and Questionnaires?1. lack of detail and answer generalisation, you rely on what's being told, not what actually happens
2. as with all self-reported data, you - 33What types of closed questions are there?1. Nominal- no quantitative value, just labels. ex: what's your gender? female/male
2. Ordinal- ORDER of answers important. measures concepts like satisfaction, happiness, discomfort.
3. Interval- interval scales that provide an order and a specific value.
4. Ratio- Everything that INTERVAL offers + calculating ratios - 343 types of INTERVIEWS and characteristics1. Structured: pre-determined questions & fixed order
2. Semi-Structured: questions determined but may be reworded, reordered or changed.
3. Unstructured: conversation has a particular focus but it develops freely
