Solution
Class boundaries in a histogram are determined by adding and subtracting 0.5 units to and from the class limits, respectively. Here's a step-by-step guide:
-
Identify the class limits: These are the smallest and largest observations in each class.
-
Subtract 0.5 units from the lower class limit: This gives you the lower class boundary.
-
Add 0.5 units to the upper class limit: This gives you the upper class boundary.
This method ensures that there are no gaps between the classes in the histogram, even when the data is continuous. It's important to note that this method is applicable when the data is represented in whole numbers. If the data is in decimal form, the unit used for adjusting the class limits will change accordingly.
