Understanding Range in Data Sets

This video tutorial covers the sixth-grade concept of summarizing numeric data, focusing on calculating the range. It explains the importance of understanding the term 'range' and how to calculate it by ordering data from least to greatest. The video also highlights common mistakes students make, such as not ordering data correctly, leading to incorrect answers. The tutorial uses a problem from the 2016 released STAAR test to illustrate these points.
