The three box plots are titled Void Ratio colon six dash millimetre Spherical Particles with drop heights of zero point three zero five metre, zero point six one zero metre, and zero point nine one five metre. The vertical axis is labelled Void Ratio, e, and ranges from zero point six four zero to zero point seven zero zero. The horizontal axis is labelled Number of Sieves with categories zero Sieve, one Sieve, two Sieves, and three Sieves. Each category contains a box and whisker plot with a median line and whiskers, and triangular markers labelled Triaxial Tests. For zero point three zero five metres, medians increase from about zero point six seven two at zero Sieve to about zero point six eight seven at three Sieves. For zero point six one zero metre, medians range from about zero point six seven two at zero Sieve to about zero point six eight one at three Sieves. For zero point nine one five metres, medians range from about zero point six six two at zero Sieve to about zero point six seven five at three Sieves.Box plot of void ratio of 6-mm diameter sphere samples comparing Number of Sieves, Void Ratio, and Drop Height
