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 average) - the sum of all data values divided by the number of the data values. deviation. - the difference between a data value in a set and the mean of the set. - the mean (average) of all deviations in a set equals zero. absolute value. - the distance (a positive quantity) of any value on a number line from zero. - the sum of the absolute values of deviations on each side of the mean are equal.
