Figure 6
Box plots summarizing jet angle data for the three different nozzle types (GDVN – 75 µm aperture, GDVN – 100 µm aperture and DFFN – 75 µm aperture), indicated in the top left-hand corner of the plots. The samples used to generate these data were the 2–4 µm lysozyme crystal sample. The table on the right-hand side shows the standard deviation (°) in the jet angle calculated over 600 images (i.e. 60 s of data collection). In the box-and-whisker plots, the lengths of the box and the whiskers represent the jet angle variation between the lower and upper quartiles (inter quartile range – IQR) and the minimum and maximum data values (excluding outliers), respectively. The position of the median value, indicated by the vertical line bisecting the box, indicates the skewness of the data (i.e. the further from the centre of the box, the more skewed the histogram). The outliers marked by the isolated data points were defined on the basis of the fact that they fall outside of the statistical limit of 1.5 × IQR. |
