HIGHLIGHTS

  • who: Yusuf F. Zakariya from the National University of Distance Education (UNED), Spain have published the research: Cronbach`s alpha in mathematics education research: Its appropriateness, overuse, and alternatives in estimating scale reliability, in the Journal: (JOURNAL)
  • what: To conclude, I recommend the use of coefficient alpha as evidence of scale reliability only after ensuring the following restrictive analytical procedures.

SUMMARY

    Some researchers have called for total abandonment of coefficient alpha (e_g, Sijtsma, 2009; McNeish, 2018), some have recommended its continuous usage under strict and verifiable assumptions (e_g, Raykov, 1997; Raykov . . .
