Which step in usability testing involves summarizing all the results from the chosen metrics?

The step in usability testing that involves summarizing all the results from the chosen metrics is the "Analysis and Reporting" step. Here's a step-by-step breakdown of the process:

1. Planning: This is where you define the scope of the test, identify the target users, and decide on the metrics you want to measure.

2. Recruiting: In this step, you find and select participants who represent your target users.

3. Test Design: Here, you create the tasks that the participants will perform during the test.

4. Test Execution: This is where the actual testing takes place. Participants perform the tasks while observers watch, listen and take notes.

5. Data Collection: Observers collect data based on the metrics defined in the planning stage.

6. Analysis and Reporting: This is the step you're asking about. Here, you analyze the data collected, summarize the results, and prepare a report. This report typically includes an overview of the findings, detailed results for each task, and recommendations for improvements.
