Study Notes
Observation in a Controlled Environment
- Direct observation involves think-aloud techniques to gather data.
- Indirect observation involves tracking users' activities using diaries, interaction logs, and web analytics.
Web Analytics
- Web analytics is a system of tools and techniques for optimizing web usage by measuring, collecting, analyzing, and reporting web data.
- It typically focuses on the number of web visitors and page views.
Choosing and Combining Techniques
- The choice of technique depends on the focus of the study, participants involved, nature of the technique, resources available, and time available.
Data Gathering
- Data gathering sessions should have clear goals.
- Five key issues of data gathering are: goals, choosing participants, triangulation, participant relationship, and pilot.
- Data may be recorded using handwritten notes, audio or video recording, a camera, or any combination of these.
Data Analysis
- Qualitative data analysis tools include categorization and theme-based analysis, and quantitative analysis of text-based data.
- Nvivo and Atlas.ti support qualitative data analysis.
Presenting the Findings
- Only make claims that the data can support.
- The best way to present findings depends on the audience, purpose, and data gathering and analysis undertaken.
- Graphical representations, rigorous notations, and using stories may be appropriate for presentation.
Summary of Data Analysis
- The data analysis that can be done depends on the data gathering that was done.
- Qualitative and quantitative data may be gathered from any of the three main data gathering approaches.
- Percentages and averages are commonly used in Interaction Design.
- Mean, median, and mode are different kinds of 'average' and can have very different answers for the same set of data.
Graphical Representations
- Graphical representations give an overview of data.
- Examples of graphical representations include charts and graphs.
Simple Qualitative Analysis
- Recurring patterns or themes emerge from data, dependent on the observation framework if used.
- Categorizing data involves using a categorization scheme that may be emergent or pre-specified.
- Looking for critical incidents helps to focus on key events.
Tools to Support Data Analysis
- Spreadsheet is a simple tool to use, with basic graphs.
- Statistical packages, such as SPSS, can be used for data analysis.
