They explain that with organic farming there is no consistency, but there is no consistency in nature. An R-squared value is a statistical measure of a correlation. It measures the degree of correlation between two things. Take humans for example, if there was consistency we would all be the same, but that is not the case and we are all different, that is why in natural biology and for statistics, an R squared value 80% is sufficient. Value is a measure of how close each value is to a fitted line. Confined farmers probably get an R-squared value above 95 percent, but organic and grass-fed farmers probably get between 80 and 90 percent, which is "nature's R." -squared value”. Basically this indicates the variability of the data, in this case the weight and size, or the distance between each data point and the line in a
