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.
One measure of spread is the mean absolute deviation (MAD) . The MAD describes the average distance between the data values in a distribution and the mean of the distribution. To compute the MAD for the menâs team, start by subtracting the value of each data point from the mean.
