What is the midpoint of the 5-9 class interval?

Explanation:
The midpoint is the value exactly in the center of the interval, found by averaging the endpoints. For 5-9, that center is (5 + 9) / 2 = 7. This sits equally distant from 5 and 9 and serves as a representative value for the class in summaries of grouped data. So 7 is the center of the interval, while 6 is closer to the lower end, 8 is near the upper end, and 7.5 would be the midpoint of 7 and 8, not of the interval 5–9.
