Class B

Both Class A and Class B

Verified step by step guidance

Step 1: Observe the dotplots for Class A and Class B. Each dot represents one student, and the x-axis represents the number of siblings.

Step 2: Focus on the number '2' on the x-axis for both Class A and Class B. Count the number of dots above '2' in each plot.

Step 3: For Class A, count the dots above '2'. There are 4 dots, indicating 4 students with 2 siblings.

Step 4: For Class B, count the dots above '2'. There are 5 dots, indicating 5 students with 2 siblings.

Step 5: Compare the counts. Class B has more students with 2 siblings than Class A.
