Here is a data set: 25.9 24.1 31 26 29 23.8 31.7 29.3 29.3 29.3 32.8 25.8 31.8 26.2 25.8 26.4 29.3 25.6 27.9 25.3 28.5 28.3 25.2 29.1 29.3 25 32.1 28 The goal is to construct a grouped frequency distribution table (GFDT) for this data set. The GFDT should have 10 classes with a "nice" class width. Each class should contain its lower class limit and each sequential lower class limit should increase by increments of the class width. This problem is to determine what the class width should be. What is the range of this data set? range = Using this value, if the goal is to have 10 classes, what is the nicest class width? optimal class width = > Next
