Percentiles represent the area under the normal curve, increasing from left to right. The area under the curve can be found by knowing the equation of the curve, the boundaries of the curve, and the axis enclosing the curve. Since the total area under the density curve is 1, that area is 1 − 0.0250 = 0.9750. The steeper the bell curve, the smaller the standard deviation. Biting pieces of flesh off arms. Standard Normal (Z) TableValues in the table represent areas under the curve to the left of Z quantiles along the margins. For example, brutal eye poking, blows to the head, face, neck, temples or mouth areas. Tearing out eye balls. If the examples are spread far apart, the bell curve will be much flatter, meaning the standard deviation is large. Now let’s come back to the ideas of area and probability. Once the calibration curve has been produced, it can be used to estimate cell counts for all samples obtained or cultured under similar conditions and with densities within the range of values used to construct the curve. A distinction is made depending on the level of detail i.e. As with any probability distribution, the proportion of the area that falls under the curve between two points on a probability distribution plot indicates the probability that a value will fall within that interval.
