When evaluating data, you can choose from various methods depending on your desired goals and indicators. Surveys are a popular option; they can be administered online or through paper and ask participants about their satisfaction, learning, engagement, or feedback. You can also use closed-ended questions (like ratings, yes/no, or multiple choice) or open-ended questions (such as comments, suggestions, or stories). Interviews are another way to get more in-depth insights from key stakeholders or participants. They can be semi-structured or unstructured and allow for flexibility and exploration of topics. Additionally, you can observe the behavior, interactions, or reactions of attendees during or after the event to gain a direct and objective view of what happened. Tests are also useful for measuring changes in knowledge, skills, or attitudes; these can be in the form of quizzes, assessments, or self-reports.
