What Apdex score indicates 'Good Performance'?

1. 0.85

2. 0.75

3. 0.95

4. 0.80

The correct answer is: 0.85

A score of 0.85 or higher generally indicates 'Good Performance' in the context of Apdex scoring. Apdex is a standard for measuring user satisfaction based on response times. It categorizes user interactions into three distinct zones: satisfied, tolerating, and frustrated. A score of 0.85 denotes that 85% of users experience an acceptable response time (satisfied) while only 15% are either tolerating or frustrated with the service. This high percentage reflects a level of performance that is typically considered satisfactory by users. Such scores indicate that the majority of users have a positive experience, which is crucial for maintaining user engagement and satisfaction. Scores below this threshold may still show some level of performance but do not meet the criteria for "good," and lower scores more distinctly suggest a higher fraction of users experiencing delays or unacceptable performance. Therefore, an Apdex score of 0.85 fits aptly into the classification of 'Good Performance'.
