Here is a data set:
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. It has been determined that the ideal class width would be 250.
This problem is to determine what the first lower class limit should be.
What is the minimum of this data set?
min =
What is the minimum divided by the class width?
minimum รท class width =
This number rounds down to what integer?
Using this value, if the goal is to have a lower class limits that are multiples of the class width, what should be the first lower class limit?
1st lower class limit =
| 4930 | 5670 | 6020 | 6350 |
| 4760 | 6560 | 5170 | 5310 |
| 5620 | 5130 | 5920 | 6440 |
| 6040 | 5310 | 5860 | 5900 |
| 5970 | 7220 | 5920 | 6020 |
| 5040 | 6580 | 5610 | 5950 |
| 4870 | 5380 | 5320 | 5870 |
