The objective of a solution implemented was to increase the number of customer calls resolved per hour.
When using basic statistical sampling concepts, what does the business analyst (BA) need to consider?

When using basic statistical sampling concepts, what does the business analyst (BA) need to consider?
When using basic statistical sampling concepts, the business analyst must consider the frequency and timing with which measurements are taken. This is because the timing and frequency of data collection can significantly impact the quality and reliability of performance measures, such as the number of customer calls resolved per hour. Understanding when and how often to collect data helps ensure that the sample accurately represents the situation being analyzed.
B is the correct answer.
8.1.4.3- Option B-Pg 168-Collect performance measures>Frequency timing
b - BABOK 8.1.4
Option A is correct. A. Metrics and Key Performance Indicators (KPIs) is what the BA will use to make meaning of the data. Frequency and Timing is only a factor that affects the quality and reliability of performance measures. BABOK says: "Frequency and Timing: the frequency and timing with which measurements are taken may have an effect on the outcome." Read Metrics, Indicator and KPI in BABOK 10.28.2.
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.
Babok page 168 8.1.4 BA may employ basic statistical sampling, ehen collecting performance measure BA may CONSIDER: volume or sample size, frequency and timing, currency
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).

The word 'technique' is not mentioned in the question
B is the correct answer
B. (8.1.4.3) When defining performance measures, business analysts may employ basic statistical sampling concepts. When collecting performance measures, business analysts consider: • Frequency and Timing: the frequency and timing with which
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.
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.
changing my mind... going with B.
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.
Frequency and Timing is the only included option here under basic statistical sampling concepts. BABOK v3, 8.1.4.3
B: BABOK Pg 168, Element 3: Frequency and Time. And the question was specific on basic statistical sampling concepts.
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.
Frequency and timing needs to be considered when collection performance measures data. (BABOK v3 8.1.4.3), not when using basic statistical sampling concepts.
