Study Notes
Planning and Running a Successful Data Gathering Program
- Decide on the goals of the data gathering program and how to analyze the data once collected
- Identify participants and decide how many are needed
- Establish a clear and professional relationship with participants
- Use triangulation to collect data from multiple perspectives and types
- Conduct a pilot study to trial the main study
Interviews
- Unstructured interviews: not scripted, rich but not replicable
- Structured interviews: tightly scripted, replicable but may lack richness
- Semi-structured interviews: guided by a script, balance between richness and replicability
- Focus groups: a group interview
Interview Questions
- Open questions: no predetermined format
- Closed questions: predetermined answer format, e.g., 'yes' or 'no'
- Avoid long questions, compound sentences, jargon, and leading questions
- Avoid unconscious biases, e.g., gender stereotypes
Running the Interview
- Introduce yourself, explain the goals, reassure about ethics, and ask to record
- Start with easy questions, then move to the main body, and end with a cool-off period
- Use digital conferencing systems like Skype, Zoom, email, and smartphones for remote interviews
- Advantages of remote interviews: participants are more relaxed, no need to travel, and easier to remain anonymous
Enriching the Interview Process
- Use props like prototypes and scenarios to prompt the interviewee
- Questionnaires: can be closed or open, closed questions are easier to analyze
Questionnaire Design
- The order of questions can impact the response
- Use different versions for different populations
- Provide clear instructions and balance white space with compactness
- Decide on question and response format: checkboxes, rating scales, open-ended responses
- Avoid very long questions and questionnaires
Encouraging a Good Response
- Make the purpose of the study clear
- Promise anonymity
- Ensure the questionnaire is well-designed
- Offer a short version for those with limited time
- Follow up with emails, phone calls, or letters
- Provide an incentive
- Aim for a 40% response rate
Online Questionnaires
- Advantages: easy to distribute, quick responses, no copying and postage costs, data can be collected in a database
- Problems: sampling is problematic if population size is unknown, preventing individuals from responding multiple times, and individuals changing questions
Deploying Online Questionnaires
- Plan the timeline, design offline, and program/complete online template
- Test the survey to ensure it behaves as expected
- Test it with a group that will not be part of the survey to ensure clear questions
- Recruit participants
Observation
- Direct observation in the field: structuring frameworks, degree of participation, and ethnography
- Direct observation in controlled environments: human-computer interaction
Data Recording
- Notes, audio, video, and photographs can be used individually or in combination
- Different challenges and advantages with each type of data recording
