10.4_Compare two dot plots

The double dot plots show the average wait times in minutes for two popular rides at an amusement park. Which ride typically has a longer wait time?

• No inference can be made from the graph.
• Topsy Turvy
• The wait times are the same for both rides.
• Rocket Blast

The dot plots show the weights of a random sample of fish from two lakes. Pick the statement that describes the variability of the samples.

• The variability of the weights of the fish in Lake S is greater than the variability of the weights of the fish in Lake R.

• The variability of the weights of the fish in the two lakes are about the same.

• The variability of the weights of the fish in Lake R is greater than the variability of the weights of the fish in Lake S.

• You cannot determine variability based on a dot plot.

If you compare the medians of each data set, who spends more time online?

• Eight graders

• Both grades spend an equal amount of time online.

• Impossible to determine form the data sets.
