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 represent 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 To access the complete dataset click the link for your preferred software format Excel Minitab JMP SPSS TI R Mac TXT PC TXT CSV Crunchlt a Obtain the five number summary of the distribution yield stresses The summary consists of the minimum Q median Q3 and maximum values in the data Enter your answers for the minimum median and maximum rounded to one decimal place Enter your answers for Q and Q3 rounded to two decimal places Note If you are using Crunchlt you may adjust the default precision under Preferences See the instructional video on how to adjust precision settings Minimum Q Median Q3 MPa MPa MPa MPa
