Question

14. In which sampling method does every member of the population have an equal chance of being selected? a. Stratified Sampling c. Random Sampling b. Systematic Sampling d. Convenience Sampling 15. What a key advantage of using a sample instead of a population? a. It provides more accurate results. c. It ensures complete data collection. b. It eliminates the need for data analysis. d It is less time consuming & less costly.

Answer 1

14. The correct answer is c. Random Sampling. In random sampling, every member of the population has an equal chance selected. This method ensures that the sample is representative of the population and reduces bias in the selection process.15. The correct answer is d. It is less time-consuming & less costly. Using a sample instead of a population has several advantages. Firstly, it is less time-consuming as it requires less effort and resources to collect data from a smaller group. Secondly, it is less costly as it involves fewer expenses in terms of data collection and analysis. Additionally, using a sample allows for more manageable and feasible data analysis compared to analyzing the entire population.
