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 Mean Absolute Deviation (MAD) of a set of data. is the average distance between each data value and the mean. The steps to find the MAD include: 1. find the mean (average) 2. find the difference between each data value and the mean. 3. take the absolute value of each difference. 4. find the mean (average) of these differences.
