For the next-to-last class, you can find the midpoint by first identifying the class range. If the class width is 10 and you’re moving back from the final class (which would typically be 90-99 considering there are 10 classes), the next to last class would be 80-89. The midpoint is calculated by averaging the lower and upper limits: (80 + 89) / 2 = 84.5.
The lower limit of this class is 80, and the upper limit is 89. So, you can state: The midpoint of the next to last class is 84.5. The lower limit of this class is 80, and the upper limit is 89.
