The Deep Dive

To find the range of Lucy's quiz scores, you need to subtract the smallest score from the largest score. First, identify the highest score, which is 92, and the lowest score, which is 64. Now, subtract: Range = Highest Score - Lowest Score Range = 92 - 64 = 28 So, the range of Lucy's quiz scores is 28. And there you have it! The range gives you a measure of how spread out her quiz scores are – a fun little statistic that tells us the variation in performance!
