How many participants were in the doodle group on average?

• A. 36.3
• B. 7.8
• C. 8.0
• D. 5.0

Answer: (A)

The average number of participants in the doodle group is 36.3. This number reflects the size of the sample that was utilized in the study to analyze the effects of doodling on memory retention and information recall. A larger sample size, such as 36.3, often contributes to more reliable data and helps in drawing general conclusions about the population being studied. In this context, having a diverse and adequately sized doodle group enhances the robustness of the findings regarding doodling's impact on cognitive processes.

Other response options, such as 7.8, 8.0, and 5.0, suggest much smaller group sizes, which may not provide the statistical power needed to effectively study the nuances of doodling behaviors and their psychological implications. Consequently, these options would not accurately reflect the scope of the research conducted.
