Elaborations
developing strategies and techniques for capturing accurate and usable qualitative and quantitative data of different formats, for example using text entry for open-ended questions to acquire qualitative data, or using radio buttons or checkboxes for closed questions to acquire quantitative data
identifying strengths and weaknesses of collecting data using different methods, for example online surveys, face-to-face interviews, phone interviews, observation, blog entries in response to a posting, phone logs, browser history and online webcam systems
