#Spss 21 how to#
You can learn how to carry out principal components analysis (PCA) using SPSS Statistics, as well as interpret and write up your results, in our enhanced content. In order to do this and then check their reliability (using Cronbach's alpha), you will first need to run a test such as a principal components analysis (PCA). If your questions reflect different underlying personal qualities (or other dimensions), for example, employee motivation and employee commitment, Cronbach's alpha will not be able to distinguish between these. This might lead us to consider whether we should remove this item.Ĭronbach's alpha simply provides you with an overall reliability coefficient for a set of variables (e.g., questions).

Removal of question 8 would lead to a small improvement in Cronbach's alpha, and we can also see that the " Corrected Item-Total Correlation" value was low (0.128) for this item. Therefore, we would not want to remove these questions.

We can see that removal of any question, except question 8, would result in a lower Cronbach's alpha. This column presents the value that Cronbach's alpha would be if that particular item was deleted from the scale. Published with written permission from SPSS Statistics, IBM Corporation. However, the procedure is identical in SPSS Statistics versions 26, 27 and 28 (and the subscription version of SPSS Statistics). Therefore, if you have SPSS Statistics versions 27 or 28 (or the subscription version of SPSS Statistics), the images that follow will be light grey rather than blue. Note: In version 27 and the subscription version, SPSS Statistics introduced a new look to their interface called " SPSS Light", replacing the previous look for versions 26 and earlier versions, which was called " SPSS Standard".
