If variable names are not assigned, SPSS Statistics provides default names that may not be recognizable. Second, each variable’s Type attribute should be specified.
Introduction
Cronbach's alpha is the most common measure of internal consistency ('reliability'). It is most commonly used when you have multiple Likert questions in a survey/questionnaire that form a scale and you wish to determine if the scale is reliable. If you are concerned with inter-rater reliability, we also have a guide on using Cohen's (κ) kappa that you might find useful.
SPSS Statistics
Example
A researcher has devised a nine-question questionnaire to measure how safe people feel at work at an industrial complex. Each question was a 5-point Likert item from 'strongly disagree' to 'strongly agree'. In order to understand whether the questions in this questionnaire all reliably measure the same latent variable (feeling of safety) (so a Likert scale could be constructed), a Cronbach's alpha was run on a sample size of 15 workers.
