Question

which of the distributions is multimodal and approximately symmetric? a. b.

Explanation:

• A multimodal distribution has more than one mode (peak). A symmetric distribution has a mirror - like quality about a central axis.
• Option A: The distribution is multimodal (two peaks) but not symmetric. The left - hand peak is taller and the shape on either side of a potential central axis is not a mirror image.
• Option B: The distribution is multimodal (two peaks) and approximately symmetric. The two peaks are of similar height and the shape on either side of the central axis (between the two peaks) is approximately a mirror image.

Answer:

B.
