State whether the following is true or false.
A higher Weibull modulus indicates a wider scatter in measured strengths.

  • A.False only at small scales
  • B.True
  • C.False
  • D.True only at large scales

Answer: C

It indicates a narrower scatter and a more uniform flaw population. The convention runs opposite to the intuition, since a larger number means a tighter rather than a broader distribution. The sign of the effect catches people out regularly.
