What can you infer about the internal consistency reliability of the new inventory ?

  • A.Satisfactory internal consistency reliability
  • B.Unsatisfactory internal consistency reliability
  • C.Split-half reliability needs to be computed first to infer about internal consistency.
  • D.Inadequate data in the above passage to infer about internal consistency.

Answer: A

The inventory shows satisfactory internal consistency reliability.

Cronbach's alpha is a direct measure of internal consistency, and a value of 0.80 is generally regarded as acceptable. No split-half coefficient has to be computed first, since alpha already gives the internal consistency, and the passage does give the data needed, so options B, C and D are wrong.
