Which activity is essential for an effective evaluation process?

Gathering quantitative data is crucial for an effective evaluation process because it provides measurable evidence that can be analyzed to assess the impact of a program or activity. Quantitative data allows evaluators to identify trends, make comparisons, and derive statistical inferences, thereby facilitating objective evaluations. This type of data can also lend credibility to the evaluation findings by presenting solid numbers that demonstrate the outcomes achieved. By relying on quantitative metrics, stakeholders can make informed decisions about program effectiveness and areas for improvement.

In contrast to options that focus on subjective feedback or process-oriented activities, accumulating quantitative data ensures that the evaluation is based on concrete evidence, allowing for more accurate assessments and recommendations.
