The other 50% will be within 2 standard deviations of the average. Looks like stats class was 50% useful in the Real-World after all... plus or minus 50%. Webnormal distribution curves fitted to the data are shown in Fig. 1. Therefore, it is reasonable to assume a normal distribution for describing the variation of individual thresholds for LF tones. total = n i i 2 i= 1 m n i i= 1 m The Statistical Distribution of Normal Hearing Thresholds for Low-Frequency Tones
