4, 1, 3, 4, 3, 4, 2, 4, 3, 1, 2, 4, 2
Make a dotplot of these data.
How good was the 2012 U.S. women’s soccer team? With players like Abby Wambach, Megan Rapinoe, and Carli Lloyd, the team put on an impressive showing en route to winning the gold medal at the 2012 Summer Olympics in London. The dotplot shows the difference in the number of goals scored in each game (U.S. women’s team – Opponent).
What percent of its games did the 2012 U.S. women's team win?
21/25 = 0.84 or about 84% of the games
4/25 = 0.16 or about 16% of the games
25/21 = 1.19 or 1.19% of the games
25/4 = 6.25 or 6.25% of the games
The following parallel dotplots show the total family income of randomly chosen individuals from Indiana (38 individuals) and New Jersey (44 individuals). Which of the following correctly compares the center of the distribution?
The Indiana distribution is roughly symmetric, while the New Jersey distribution is right-skewed.
The distribution for Indiana has a similar center to the distribution for New Jersey, around $45,000.
The variability for Indiana is less than the variability for New Jersey.
$125,000 appears to be an outlier for the Indiana distribution and there isn't any obvious outliers for the New Jersey distribution.
Who might be the individuals in this dotplot?
cereals
volcanos
students
grandparents

Both dotplots appear to have outliers.
The time spent on video games had a greater range than the time spent on exercise.
What is NOT true about the graph above?
There is an outlier in the Cat Owners data.
There is an outlier in the Dog Owners data.
There is a peak of 7 in the Cat Owners data.
There is a peak of 5 in the Dog Owners data.
