Being able to calculate linearity (or correlation, as it's often referred to) is a very valuable skill. Linearity is a quantitative assessment of how strongly related a set of data is. Linearity ranges from 0 (not related at all) to 1 (completely related) and gives a useful numerical gau...
The correlation coefficient, or r, always falls between -1 and 1 and assesses the linear relationship between two sets of data points such as x and y. You can calculate the correlation coefficient by dividing the sample corrected sum, or S, of squares for (x times y) by the square root...
