Sample cronbach analysis using kara

  1. 1. Sample Cronbach Analysis using Kara.sav Aiden Yeh Wenzao Ursuline University
  2. 2. Follow the highlighted texts
  3. 3. Living Standard Category (Construct)
  4. 4. Click ‘Statistics’, choose ‘item, scale, scale if deleted, and correlations • Click continue, • then click ‘ok’ to produce output
  5. 5. • Pretty low Cronbach alpha of . 571 for this sample size of 110 (N=110)
  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
  9. 9. • In a case where the [internal consistency] reliability is somewhat low, you may still want to sum the scores (count/frequency)
  10. 10. • In a case where the [internal consistency] reliability is somewhat low, you may still want to sum the scores (count/frequency)
