Dot Plots Center and Spread

What is the difference between the medians for the two data sets? 

• 0 tickets

• 2 tickets

• 4 tickets

• 6 tickets

Compare the centers and spreads. 

•  Math has a higher median (center) and a wider spread.

•  Math has a higher median (center) and a smaller spread.

• Math has a lower median (center) and a smaller spread.

• Math has a lower median (center) and a wider spread.

The double dot plots show the average wait times in minutes for two popular rides at an amusement park. Compare the measures of center and variation, 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 compare the number of raffle tickets sold by boys and girls during a school fund-raiser. Which plot has an outlier? 

• Girls

• Boys

• Both Plots

• Neither

Members of the drama club are getting measured for costumes. The dot plot below shows the height of distribution of the club in inches. Which statement about the data is true?

• The median is 54.5 and the IQR is 2.5"

• The median is 54 and the IQR is 2.5”

• The median is 53.5 and the IQR is 2”

• The median is 55 and the IQR is 3”

How is the center of spread in a box plot different from that in a dot plot?

• A box plot uses the median as the center, while a dot plot uses the mean.

• A box plot shows the center as a line, while a dot plot does not explicitly show the center.

• A box plot cannot show the center of spread, while a dot plot can.

• There is no difference in how they show the center of spread.

These two dot plot shows the daily low temperatures for two cities for 15 days. Which city has a greater amount of VARIATION in temperatures?

• Both dot plots are bell shaped so they have the same variation.

• Lahnston has greater variation because the range in temperature for Lahnston is greater than for Zaslow.

• The dot plots are for different cities so we can't say.

• Zoslow has greater variation because the range in temperature for Zoslow is greater than for Lahnston.

In a dot plot, how is the spread of the dataset visually represented?

• By the height of the dots

• By the width of the plot

• By the distance between the dots

• By the color of the dots
