The dot plots below show the ages of students belonging to two groups of salsa classes. Based on visual inspection which group most likely has a lower mean age of salsa students

1 answer

Group 1 most likely has a lower mean age of salsa students. This is because the dot plot for Group 1 shows a cluster of data points around the lower ages, while the dot plot for Group 2 shows a more spread out distribution of ages, including some higher ages. This suggests that Group 1 has a lower overall average age compared to Group 2.
