This document contains data with two columns of numbers and calculations of the mean (Mx), sum of squares from the mean (f(X-Mx)), and standard deviation (SR). The data includes 6 rows of paired values ranging from 4 to 9 in the first column and 5 to 10 in the second column. The mean of the first column is calculated as 6.2, and the standard deviation is calculated as 1.19 based on the sums of squares from the mean.
