A left-skewed distribution has a tail to the left and a peak dislocated to the right.
A right-skewed distribution has a tail to the right and a peak dislocated to the left.
A symmetrical or approximately symmetrical distribution has a peak at the center of the distribution, and bars that are equidistant from the center have approximately the same height.
As we can see, the given distribution has a peak at the center of the distribution and the bars equidistant from the center have approximately the same height.
Therefore, the distribution is approximately symmetrical.
