How to determine class boundaries in statistics?
Understand the Problem
The question is asking about how to establish or calculate class boundaries in statistics. Class boundaries are used to define the ranges of data values that fall into different categories or classes, typically in a frequency distribution. This involves knowing how to adjust the upper and lower limits of each class to avoid overlap.
Answer
Subtract 0.5 from the lower class limit and add 0.5 to the upper class limit.
To determine class boundaries, subtract 0.5 from the lower class limit and add 0.5 to the upper class limit.
Answer for screen readers
To determine class boundaries, subtract 0.5 from the lower class limit and add 0.5 to the upper class limit.
More Information
Class boundaries are used to ensure there are no gaps between the intervals in a frequency distribution, allowing for accurate data representation.
Tips
A common mistake is misapplying the subtraction and addition; make sure to refer to the correct class limits for accurate boundaries.
