For each picture and description:
The distribution is bell-shaped since there is a central peak for symmetric data that is less frequent on the ends.
The distribution is symmetric because if the distribution were cut in half, both sides would be the same shape.
The distribution is uniform because there seems to be the same amount of data points across the entire distribution.
The distribution is symmetric because if the distribution were cut in half, both sides would be the same shape.
The distribution is skewed left since most of the data is on the left side of the distribution.
Describe the shape of each distribution using the term ”approximately,” “symmetric,” “bell-shaped,” “skewed left,” “skewed right,” “uniform,” or “bimodal.” Estimate the center of each distribution.
