Understanding Box Plots and Quartiles

The video tutorial covers the sixth-grade concept of representing numeric data using box plots, as per Texas standard 6.12a. It uses a problem from the 2022 STAR test to demonstrate how to organize data, find the range, calculate the median, and identify quartiles. The tutorial guides students through each step, ensuring they understand how to represent data visually and interpret box plots effectively.
