Understanding Frequency Tables and Intervals

This video tutorial from M math explains how to set up a frequency table using intervals. It covers the importance of having equal, nonoverlapping intervals that encompass all data points. The tutorial demonstrates how to calculate the range, divide it into intervals, and tally data points to create a frequency table. The video also provides examples of different interval setups and emphasizes the need for accuracy in data representation.
