From Right to Left it Had No End: Cronbach Alpha Analysis
It is common in research to attempt the measurement of variables for which there is no universally agreed measure. Any variable measurement, but especially data open to different interpretations, such as crime scene actions, must be queried as to its reliability in terms of producing the same results on different occasions. In order to establish, on an empirical level, that the crime scene variables used in this study are structured into meaningful themes with similar psychological meanings, it was necessary to determine that the variables are indeed measuring related phenomena within each theme. Selecting items to form an appropriate scale is therefore a very important step that is both theoretically and technically sound. An appropriate test for measuring related phenomena is Cronbach’s Reliability Alpha Scale. A moderate Alpha scale measure is.60. Variables in each theme were submitted to Cronbach’s Alpha Analysis. A total of 55 crime scene actions were analyzed. Variab...
