Question

The dot plots below show the ages of students belonging to two groups of painting classes: Based on visual inspection, which group most likely has a lower mean age of painting students? Explain your answer using two or three sentences. Make sure to use facts to support your answer.

Answer 1

To determine which group most likely has a lower mean age of painting students based on the dot plots, compare the central tendencies and spread of the dot plots.

Step-by-step explanation:

To determine which group most likely has a lower mean age of painting students based on the dot plots, we need to look at the central tendency of each group. The group with a dot plot that is shifted more to the left or has a smaller range of ages is likely to have a lower mean age.

For example, if Group A has a dot plot that is more clustered around ages 15-20, while Group B has a dot plot that is more spread out from ages 18-25, then Group A is likely to have a lower mean age.

By visually inspecting the dot plots and comparing the spread and position of the dots, we can make an inference about which group most likely has a lower mean age of painting students.
