6. For the purposes of determining if certain values per hectare must, by statistical deletion, be removed from the basic list, the following operations are performed successively:(1) determine the median value of the basic list;
(2) subtract the median value determined in accordance with subparagraph 1 from each value per hectare on the basic list;
(3) square each difference that results from the subtraction provided for in subparagraph 2;
(4) add all the squares obtained in accordance with subparagraph 3;
(5) divide the sum resulting from the addition provided for in subparagraph 4 by the number, lowered by one, of values per hectare on the basic list;
(6) establish the square root of the quotient that results from the division provided for in subparagraph 5;
(7) subtract the double square root established in accordance with paragraph 6 from the median value determined in accordance with subparagraph 1;
(8) add the median value determined in accordance with subparagraph 1 and the double square root established in accordance with subparagraph 6.
For the purposes of subparagraph 1 of the first paragraph, the values on the basic list are classified in ascending order. The median is established in the classified group using the following equation:n / N < 0.5 and (n+1) / N ≥ 0.5 Where:
n = Position of the value per hectare in the group;
N = Total number of values per hectare in the group.
For the purposes of the operations provided for in subparagraphs 5 and 6 of the first paragraph, when the result contains a decimal, it is rounded up to the nearest unit if it is equal to or greater than 5 or, if not, it is rounded down to the nearest unit.
