ACCA Performance Management (F5) Certification Practice Exam

What are some main types of measurement techniques?

1. Focus groups and interviews

2. Random sampling and primary data collection

3. Random sampling and quota sampling

4. Surveys and case studies

The correct answer is: Random sampling and quota sampling

The selection of random sampling and quota sampling as the correct answer highlights two established methods crucial in data collection and analysis. Random sampling is a technique used to ensure that every member of a population has an equal chance of being selected, which helps to eliminate bias and allows for generalization of results to the larger population. This method is foundational in research as it enhances the validity and reliability of the findings. Quota sampling, on the other hand, involves segmenting the population into subgroups and then non-randomly selecting participants from those groups to ensure that specific characteristics or demographics are represented in the sample. This method is useful for ensuring that particular segments of the population are included in the study, which can enhance the depth and relevance of the analysis. Both techniques are critical in performance management when assessing data and making informed decisions based on a comprehensive understanding of different segments of a population. While focus groups and interviews provide qualitative insight, they do not represent standardized measurement techniques akin to the statistical nature of random and quota sampling. Surveys and case studies, while valuable forms of data collection, also do not specifically highlight the measurement techniques like random and quota sampling, which are more aligned with designing studies aimed at quantifiable measurement and analysis.
