Normality was verified using the Shapiro Wilk test and through visual examination of histograms with normal curve, and normality plots.
The Shapiro Wilk test was performed to evaluate the variables' adherence to a normal curve, where all showed normality (P < 0.05).
One characteristic that defines the normal distribution is that normally distributed data will have the same amount of area of normal curve between each point.
(A leptokurtic curve has a higher peak and fatter tails than a normal curve).
The green lines define the area in which a normal curve is expected to fall.
Given the model of the normal curve, there should probably be more Bs than As, and more Bs than Cs.
"The bell-shaped Gaussian (normal) curve appears ubiquitously in scientific data, and it is natural to wonder why," says Oliver Johnson, reader in information theory at the University of Bristol.
Abbott implied that the rest were young men in a hurry when she referred to them as "geeks in suits", yet all of them are outside the normal curve, however one plots its co-ordinates.
For each gel sample, cumulative particulate size distribution of model bolus was reduced logarithmically with a normal curve regardless of the addition level of saliva.
Adherence test to the normal curve was performed.
Each histogram is fitted by a normal curve.
