Box Plot of JVA Data. The item score is the logarithm base 10 of the original data. These data, based on all 36 subjects, largely corrected the skewed distributions. The items are TI: total integral, IGr300: integral greater than 300Â Hz, R: ratio of integral >300 to integral <300, ILs300: integral less than 300Â Hz, PA: peak amplitude, MF: median frequency, PF: peak frequency
