The number of participants | Few (dozen(s)). As many as you can personally observe/listen to. |
What we are collecting | Records of actions in any human-readable format: video, user sessions of the webviewer, log of actions, your notes in a notebook, etc. |
Analysis | A basic analysis model: we observe -> we note what we observe -> we notice any trends and group them into themes, then summarise. |
The range where it can be applied | Define the hypothesis: which problems do consumers or users face and how their experiences can be improved. |

The range where it can be applied | Define the hypothesis: which problems do consumers or users face and how their user experiences can be improved. |
The number of participants | Hundreds or thousands. Enough to provide statistically reliable results. |
What we are collecting | A database with answers, tables with percentages or counts, distribution of answers. |
Analysis | A simple analysis of the distribution of responses. For some tasks a more complex type of analysis may be required, such as cluster analysis, factor analysis, regression, etc. |
The range where it can be applied | Testing the hypothesis. Assessing the size of the need / problem. Assessing market potential of a product or a feature. Prioritising. Selecting the best alternative. Evaluation of results. |
The number of participants | Hundreds. Enough to provide statistically reliable results. |
What we are collecting | A database with facts of participant behavior in a simulated situation, tables with distribution percentages of patterns of behavior. |
Analysis | A simple analysis of the distribution of responses. For some tasks a more complex type of analysis may be required, such as cluster analysis, factor analysis, regression, etc. |
The range where it can be applied | Testing the hypotheses, selecting the best option. The results of the experiment can be used to determine the relative importance of the problems or to tell which of the two tested options is better. |
