WebThe pattern deviation map takes the difference between each observed threshold and the average threshold across the entire field and displays the difference between these values and age-specific normal threshold differences at each location. WebThe first step is to subtract the mean from each data point. Then square the absolute value before adding them all together. Now divide by 9 (the total number of data points) and finally take the square root to reach the standard deviation of the data: [Figure 2: The step-by-step process of finding the standard deviation of sample data]
