Two students were practicing the use of a scale. They each weighed an identical object 5 times. Student A got weights of 103, 104, 105,106, and 107 pounds for the object, and student B got 101, 103, 105, 107, and 109 pounds for the same object. Which of the following statements best describes the average and variation in their results?
A. Student B got a higher average weight than student A and higher range.
B. Student B got a higher average weight than student A and the same range.
C. The two students got the same average weight and each had 5 measurements so the variability was the same.
D. The two students got the same average weight, but student B had a higher range of measurements and more variability.
