Answer

Explanation:

Step1: Identify the modes

Count the frequencies of scores in different intervals. We see higher - frequency intervals around the 60 - 69 and 70 - 79 ranges, indicating two modes.

Step2: Check for symmetry

The distribution of scores on either side of the center (around the modes) appears to be relatively balanced. There is no significant tail on one side.

Answer:

bimodal and symmetric
