What the Standard Deviation tells us about ginger

, Unit 6 C+D Project Implementation and Review
68% of all clear zones’ areas measured in all trials should fall within 1 standard deviation
of the mean.
(i.e., for 100%, 68% of all areas measured will have an area between 678.5 mm 2 and
286.3 mm2)
95% of all areas measured should have an area in the range of 2
standard deviations from the mean, i.e., for 100%, they should be
between 874.6 – 90.2 mm2
68% of all clear zones’ areas measured in all trials should fall
within 1 standard deviation of the mean.
(i.e., for distilled water, 68% of all areas measured will have an
area between 0.0 mm2 and 0.0 mm2)
95% of all areas measured should have an area in the range of 2
standard deviations from the mean, i.e., for 100%, they should be
between 0.0 – 0.0 mm2
68% of all clear zones’ areas measured in all trials should fall
within 1 standard deviation of the mean.
(i.e., for 1%, 68% of all areas measured will have an area between 6.4 mm 2 and 53.8
mm2)
95% of all areas measured should have an area in the range of 2 standard deviations
from the mean, i.e., for 100%, they should be between 0.0 – 77.5 mm 2
68% of all clear zones’ areas measured in all trials should fall within 1 standard deviation
of the mean.
(i.e., for 10%, 68% of all areas measured will have an area between 107.3 mm 2 and 72.1
mm2)
95% of all areas measured should have an area in the range of 2 standard deviations
from the mean, i.e., for 100%, they should be between 54.5 – 124.9 mm 2
What the Standard Deviation tells us about hand sanitizer
68% of all clear zones’ areas measured in all trials should fall within 1 standard deviation
of the mean.
(i.e., for 100%, 68% of all areas measured will have an area between 74.9 mm 2 and 102.5
