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.
So the mean absolute deviation (from the mean) is 3.6. In other words, the sample points are, on average 3.6 units from the mean. For more information visit the Related Links. The Mean Absolute Deviation is calculated in three simple steps. Alternatively , you can use the excel formula =AVEDEV(56,78,90) to obtain the result. There are different formulas for the calculation of mean absolute deviation. For example mean absolute deviation from mean and mean absolute deviation from median.
