• A
  77% (27)

  9% (3)
• C
  11% (4)
• D
  3% (1)

Explanation

Sample size is the number of observations or data points that are used to measure the performance of a solution. Sample size is an important consideration for the BA to obtain reliable and valid information, as it affects the accuracy, precision, and confidence of the results. A larger sample size can reduce the sampling error and increase the representativeness of the population, but it may also increase the cost and time of data collection. A smaller sample size can save resources and time, but it may also introduce bias and uncertainty in the results. Therefore, the BA should determine the appropriate sample size based on the purpose, scope, and quality criteria of the performance measurement12. The other options are not directly related to the data collection process, although they may influence the analysis and interpretation of the data.
