Which ONE of the following options describes a scenario of A/B testing the LEAST?

SELECT ONE OPTION

Show Suggested Answer Hide Answer
Suggested Answer: C

A/B testing, also known as split testing, is a method used to compare two versions of a product or system to determine which one performs better. It is widely used in web development, marketing, and machine learning to optimize user experiences and model performance. Here's why option C is the least descriptive of an A/B testing scenario:

Understanding A/B Testing:

In A/B testing, two versions (A and B) of a system or feature are tested against each other. The objective is to measure which version performs better based on predefined metrics such as user engagement, conversion rates, or other performance indicators.

Application in Machine Learning:

In ML systems, A/B testing might involve comparing two different models, algorithms, or system configurations on the same set of data to observe which yields better results.

Why Option C is the Least Descriptive:

Option C describes comparing the performance of an ML system on two different input datasets. This scenario focuses on the input data variation rather than the comparison of system versions or features, which is the essence of A/B testing. A/B testing typically involves a controlled experiment with two versions being tested under the same conditions, not different datasets.

Clarifying the Other Options:

A . A comparison of two different websites for the same company to observe from a user acceptance perspective: This is a classic example of A/B testing where two versions of a website are compared.

B . A comparison of two different offers in a recommendation system to decide on the more effective offer for the same users: This is another example of A/B testing in a recommendation system.

D . A comparison of the performance of two different ML implementations on the same input data: This fits the A/B testing model where two implementations are compared under the same conditions.


ISTQB CT-AI Syllabus, Section 9.4, A/B Testing, explains the methodology and application of A/B testing in various contexts.

Yeah, C is more about dataset comparison, not user testing.

I’m leaning towards option C as the least A/B testing scenario, but I’m not entirely confident. It feels like it’s more about dataset comparison than user response.

I practiced a similar question where we had to identify A/B testing scenarios, and I feel like option D might be the least related since it’s about different implementations, not variations.

I think options A and B are definitely A/B testing scenarios, but I'm a bit confused about option C. It seems more like a performance evaluation than a true A/B test.

I remember A/B testing is about comparing two variations to see which performs better, but I'm not sure if comparing ML systems fits that definition.
