Exam CBAP topic 1 question 305 discussion

B is the correct answer.

8.1.4.3- Option B-Pg 168-Collect performance measures>Frequency timing

When using statistical sampling to evaluate the number of customer calls resolved per hour, the frequency and timing of data collection are crucial factors. The business analyst (BA) needs to determine: • Frequency: How often data is collected (e.g., hourly, daily, weekly). • Timing: When data is collected (e.g., peak vs. off-peak hours). By considering these factors, the BA can ensure that the sample data is representative of real-world performance. This helps avoid skewed or biased results, ensuring that any conclusions drawn about call resolution rates are accurate and reliable.

Metrics and KPIs is correct answer. As per BABOK v3 8.1.4.3, when defining performance measures (which may be called as KPIs or metrics), business analyst may employ basic statistical sampling concepts. So reversely, when employing basic statistical sampling concepts, BA need to consider defining performance measures.

B: BABOK Pg 168, Element 3: Frequency and Time. And the question was specific on basic statistical sampling concepts.

While frequency and timing (Option B), financial analysis (Option C), and benchmarking and market analysis (Option D) may also provide valuable insights, they are not specifically focused on basic statistical sampling concepts, which are more directly applicable to measuring and evaluating performance metrics such as the number of customer calls resolved per hour. Therefore, Option A is the most relevant choice in this context.

Frequency and Timing is the only included option here under basic statistical sampling concepts. BABOK v3, 8.1.4.3

8.1.4: When defining performance measures, business analysts may employ basic statistical sampling concepts: • Frequency and Timing: the frequency and timing with which measurements are taken may have an effect on the outcome.

8.1.4: When defining performance measures, business analysts may employ basic statistical sampling concepts..... When collecting performance measures, business analysts consider: • Volume or Sample Size: a volume or sample size appropriate for the initiative is selected. A sample size that is too small might skew the results and lead to inaccurate conclusions. Larger sample sizes may be more desirable, but may not be practical to obtain. • Frequency and Timing: the frequency and timing with which measurements are taken may have an effect on the outcome. • Currency: measurements taken more recently tend to be more representative than older data.

Frequency and Timing is not a technique. But in Metrics and Key Performance Indicators (KPIs) you can use Frequency and Timing as base. So answer is A. Metrics and key performance indicators measure the performance of solutions, solution components, and other matters of interest to stakeholders (like Frequency and Timing).

B is the correct answer

It's B, Frequency and Timing

question says "when using basic statistical sampling concepts" - B has to be the answer. while taking sampling time and frequency is the key consideration. That's the essence of a sampling process. The answer has to be B.
