Group variation and dynamics can lead to extreme variation in results.

c.

Group experiments typically involve more participants.

d.

Group experiments focus on individual performance.

Answer: (b).Group variation and dynamics can lead to extreme variation in results. Explanation:Group variation and dynamics can lead to extreme variation in results, making it challenging to find statistically significant differences between experimental conditions in group experiments.
