Question

Analyze a frequency distribution table and find the midpoint of each value interval.

value interval frequency 0-3 5 4-7 6 8-11 13 12-15 1

Answer 1

To find the midpoint of each value interval in a frequency distribution table, calculate the average of the lower and upper boundaries of each interval.

Step-by-step explanation:

To find the midpoint of each value interval in a frequency distribution table, we need to calculate the average of the lower and upper boundaries of each interval. For example, in the interval 0-3, the lower boundary is 0 and the upper boundary is 3. So, the midpoint is (0 + 3) / 2 = 1.5. Similarly, for the interval 4-7, the midpoint is (4 + 7) / 2 = 5.5. The midpoints for the remaining intervals can be calculated in the same way.
