Spider silk is the strongest known material, natural or man-made, on a weight basis. A study examined the mechanical properties of spider silk using 21 female golden orb weavers, Nephila clavipes. The data on silk yield stress represents the amount of force per unit area needed to reach permanent deformation of the silk strand. The data are expressed in megapascals (MPa). 164.0 478.7 251.3 351.7 173.0 448.9 300.6 362.0 272.4 740.2 329.0 327.2 270.5 332.1 288.8 176.1 282.2 236.1 358.2 270.5 290.7 (a) Use the software of your choice to make a dotplot of these data.
