Let's say you're measuring a continuous variable such as height or speed. You collect tally charts with classes 30 - 39, 40 - 49, 50 - 59 etc.
49 would be an upper class limit, but 49.5 would be an upper class boundary, since a reading of 49.4 for example falls outside the class limits.

To calculate the class boundary of the first class in statistics, subtract 0.5 from the lower class limit of the first class and add 0.5 to the upper class limit of the first class. This is done to account for the fact that class boundaries fall halfway between the class limits.
class boundary is 4.4 class limit is either 3.9 or 4.9
class boundary is 48.6 class limit is either 48.1 or 49.1

There is abig difference between them..gamma is a distribution but central limit theorm is just like a method or technique u use to approximate gamma to another distriution which is normal....stupid
