(i) asking how companies use their websites

Open-Ended Surveys

[ Open-ended questions are defined as free-form survey questions that allows a respondent to answer in open text format such that they can answer based on their complete knowledge, feeling, and understanding. ]

(ii) asking colleagues for their views on a proposed change to working conditions

1-on-1 Interviews

Direct observation

[ In direct observation the data collector takes a participatory stance, observing the setting in which the subjects of their observation are while taking down notes, video/audio recordings, photos, and so on. ]

(iv) testing the accuracy of invoices.

Closed-ended Surveys
