  6. 6. Look at the "Cronbach's Alpha if Item Deleted" • Corrected item-total correlation for Japan111 is very, very low at .081, which means you may remove this item • Nonetheless, your reliability factor for this scale is still very poor
  7. 7. • A low value of alpha could be due to a low number of questions, poor interrelatedness between items or heterogeneous constructs. • For example if a low alpha is due to poor correlation between items then some should be revised or discarded. • items with low correlations (approaching zero) are deleted.
  8. 8. • A reliability of .5 means that about half of the variance of the observed score is attributable to truth and half is attributable to error. • Low Cronbach's alpha also means that a group of people did not respond to that set of items consistently
