In statistics, the range is the value of the largest number in a set minus the smallest number in the set. All four groups of student SAT scores have similar ranges, however the largest range is group 2 with a range of 850.

Answer:

Group 2 has the greatest range

Step-by-step explanation:

From the data given we can find the range by this formula :

Range = Largest score - smallest score

Range of group 1 = 1700 - 1300 = 400

Range of group 2 = 2100 - 1250 = 850

Range of group 3 = 2000 - 1390 = 610

Range of group 4 = 2150 - 1340 = 810

400 < 610 < 810 < 850

Therefore, we can see that students of Group 2 has the greatest range.
