Note that the total number of ranges is one less than the number of samples. This is because the first moving range that can be calculated is between the first and second samples, so there will always be one less range value than the number of samples. As before, divide the SUM R value by the number of ranges (24), and enter the result in the box outlined in red. Please round your answer to 1 decimal place.
