Specimens of three different types of rope wire were
selected, and the fatigue limit (MPa) was determined for
each specimen, resulting in the accompanying data.
Type 1 350 350 350 358 370 370 370 371
371 372 372 384 391 391 392

a. Construct a comparative boxplot, and comment on
similarities and differences.
b. Construct a comparative dotplot (a dotplot for each
sample with a common scale). Comment on similarities
and differences.
c. Does the comparative boxplot of part (a) give an
informative assessment of similarities and differences?
