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.
