This case is one of the number (for this frequency) of cases having 70 to 80 percent of its energy in the primary mode. 210. Results of this computation are shown in Figure 24, which is a cumulative bar chart like Figure 23. This figure indicates that in a band of low frequencies from about to Hz, 95 to 99 percent of all cases (read from the %-of-cases axis) have 90 to 100 percent (black-shaded bars) of total energy in the primary mode. Note that this includes the unimodal cases, which identically have 100 percent of energy in the primary (only) mode. At the highest frequency, fewer than 20 percent of all cases have 90 to 100 percent of energy in the primary mode. At this same frequency, an addi- tional 5 percent (or so) of all cases have 80 to 90 percent of energy in the primary mode, a further 7 percent (or so) of all cases have 70 to 80 percent 60%-70% ^m 30%-40% 50%-60% ^^ 20%-30% 40%-50% 1046 Cases.
