Lung nodules are usually about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size. A larger lung nodule, such as one that's 30 millimeters or larger, is more likely to be cancerous than is a smaller lung nodule.
In statistics, mean absolute deviation is a one of the ways to describe the variability of quantitative data. Mean absolute deviation is used to measure the average amount by which all values in a data set vary from their mean.
The absolute uncertainty (usually called absolute error-but error connotes mistake, and these are NOT mistakes) is the size of the range of values in which the true value of the measurement probably lies. If a measurement is given as, the absolute uncertainty is 0.1 cm.
