You can put this solution on YOUR website! how to get the upper limit of the last class if adding class width to the lower limit of the last class did not reach the highest data. for example my class width is 7 and my last lower limit is 29.8 adding another 7 and reducing by 0.1 to get the upper limit will get 36.7.. but my highest data is 38.3. what should i do?
----
Data: 29.8,30,31,32,33,34,36,38,38.3
Find the range: 38.3-29.8 = 8.5
Divide by number of classes: 8.5/5 = 1.7 = class width
---
lowest lower limit: 29.8
29.8 to 31.5
31.5 to 33.2
33.2 to 34.9
34.9 to 36.6
36.6 to 38.3
