Understand Measures of Center and Variation Practice Test

Two basketball teams tracked their points scored in 6 games. Team A scored: 45, 48, 47, 46, 49, 45 points. Team B scored: 35, 55, 40, 60, 38, 52 points. Both teams have the same mean score of 47 points. What can you conclude about the variation in their performance?

A scientist collected data on plant heights (in cm): 12, 15, 18, 14, 16, 13, 17, 15, 16, 14. She calculated the mean as 15 cm and the range as 6 cm. Her assistant claims that since the mean equals one of the data values (15), the variation must be very small. How should the scientist respond to evaluate this claim about measures of center and variation?
