The bulk density of soil (x, in g/cm3) affects plant growth, specifically, how easily roots can penetrate the soil. A group of carrot growers conducted a study to compare soil bulk density with soil texture (y), measured on a scale from 1 to 10, with 1 being very sandy soil and 10 corresponding to clay. A random sample of plots was obtained, and the data were recorded. Compute Spearman's rank correlation coefficient, and use this value to describe the relationship between these two variables.
