A pre(cid:448)ious (cid:455)ear"s figure, (cid:373)easures fro(cid:373) other pla(cid:272)es, a (cid:271)e(cid:374)(cid:272)h(cid:373)ark, a goal, et(cid:272). Make sure your comparison is weighing two similar types of values. When reporting numbers, provide the comparison and context. About 40 percent of male students passed the test compared to 55 percent of female students. Per capita and related calculations allow comparisons among groups of different sizes. Ranking should include raw numbers to provide a sense of relative importance. When comparing dollar amounts across time, be sure to adjust for inflation or seasonal adjustment (look for formulas to do this). Actual change: when measuring actual change over time, subtract the older number from the newer number. However, this raw measure of difference may not be the best way to convey change. For e(cid:454)a(cid:373)ple, if a to(cid:449)(cid:374)"s (cid:271)udget (cid:449)e(cid:374)t up 200 million from one year to the next, that may not tell much.
