How many participants were included in the practical study?

• A. 5
• B. 10
• C. 15
• D. 20

Answer: (B)

In the context of a practical study, the numerical value that represents the number of participants is crucial as it can significantly affect the validity and reliability of the research findings. A sample size of ten participants is often chosen for practical studies because it allows researchers to gather enough data for preliminary analysis while still being manageable in terms of time and resources.

This size can also offer a balance between providing diverse perspectives without overwhelming the researchers with data that may be more complex to analyze accurately. In many psychological studies, a group of ten participants can help identify trends and potential correlations while still being small enough to maintain a controlled environment for the practical aspects of the research. Thus, ten participants was likely the number needed in this case to draw meaningful conclusions while remaining practical.
