Here is a data set: 490 378 149 397 412 315 252 306 238 248 256 235 300 140 49 311 125 348 257 293 318 207 251 65 275 123 247 49 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 the lower class limits should all be multiples of the class width. This problem is to determine what the class width should be.

Expert Solution
Step 1

Given information:

The data set is provided as:

490 378 149 397
412 315 252 306
238 248 256 235
300 140 49 311
125 348 257 293
318 207 251 65
275 123 247 49

It is required to obtain the class width (h) for the k = 10 classes to make a group frequency distribution table.
