Here is a data set:
2900 20500 11000 10100
13700 12800 7300 16500
12900 2200 18000 21600
13700 5800 13700 7700
12300 12500 12600 5700
8900 8300 14500 6600
14900 20900 11200 9100


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 and the first lower class limit should be.

What is the best class width for this data set?
optimal class width =

What should be the first lower class limit?
1st lower class limit =
