Oh, dude, class intervals are the ranges that group data together in a frequency distribution, like 1-10, 11-20, etc. Class width is just the difference between the upper and lower boundaries of each class interval. So, basically, class intervals are like the neighborhoods where data hangs out, and class width is just the size of the houses in those neighborhoods.

The difference between any two consecutive lower (or upper) class limits it the class width.

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.
