(1/2) The graph to the right shows the number of cities with certain average annual rainfall amounts (in inches). Identify the level of measurement of the data listed on the horizontal and vertical axes in the graph. A bar graph has a horizontal axis labeled " Number of cities " with classes A through E and a vertical axis labeled " Annual rainfall " from 0 to 50 in increments of 10. The classes are as follows, with the label listed first and class second: A, 1; B, 2; C, 3; D, 4; E, 5. There are vertical bars with labels and heights as follows: A, 28; B, 16; C, 14; D, 21; E, 21.ABCDE01020304050Annual rainfall A: 1 B: 2 C: 3 D: 4 E: 5 Identify the level of measurement of the data listed on the horizontal axis in the graph. Choose the correct answer below.
