Answer:
The left side of the data looks similar to the right side in the seventh-grade data, but not in the fifth-grade data.
Step-by-step explanation:
In the seventh-grade data, we can split dots into two equal groups, one from 0 to 3 and the other one from 4 to 7. In the first group the dot distribution is {2, 2, 3, 5}. In the second group the dot distribution is {5, 3, 3, 1}. Then, the left side looks similar to the right side (they are symmetrical).
If we perform a similar division between dots for fifth-graders data, we obtain one group, from 1 to 4, which dot distribution is {2, 3, 1, 4}; and another group, from 5 to 8, which dot distribution is {5, 5, 2, 2}. Then, the left side doesn't look similar to the right side (they aren't symmetrical).
