Skewed Distributions Dot Plots

The dotplot shows the results of rolling a pair of 6-sided dice and finding the sum of the up faces 100 times. Determine if the dotplot is roughly symmetric or skewed.

• Roughly symmetric

• Left-skewed

• Right-skewed

• None of the above

The dotplot shows the results of rolling a pair of 6-sided dice and finding the sum of the up faces 100 times. Describe the peak(s) of the graph.

• Clear peak at 7

• Clear peak at 2

• There are multiple peaks at 6 and 7

• There are no peaks

The dotplot shows the results of rolling a pair of 6-sided dice and finding the sum of the up faces 100 times. Describe the clusters or gaps of the graph

• There is a cluster from 6 to 8.

• There is a gap from 13 to 14

• There are no gaps or clusters to describe

• I don't know what a gap or cluster is.
