Question

The values on the horizontal axis range from 3 to 7 in increments of 1. The values on the vertical axis range from 0 to 12 in increments of 2. The frequency per number of classes is as follows: 3 classes, frequency 1; 4 classes, frequency 6; 5 classes, frequency 12; 6 classes, frequency 6; and 7 classes, frequency 1.

The median is in the bin 10-14.9

Answer 1

Total frequency = 1+6+12+6+1 = 26, so the median is the average of the 13th and 14th observations. Cumulative frequencies: up to 3 = 1, up to 4 = 7, up to 5 = 19. Both the 13th and 14th values fall in the class 5, which corresponds to the bin 5–9.9.

Answer: The median is in the bin 5-9.9.
