Finding the Range from a Table Worksheet Download
The values deliberately include REPEATS and are never in order, because a sorted table puts the largest and smallest in the first and last rows and leaves nothing to do. The wrong answers are the numbers a student actually lands on - the range with the largest value missed, the range with the smallest missed, the count of different values, and one either side of the right answer - so the answer cannot be found by noticing which choice is small. The unit follows the context: a range of points is not a range of degrees.
