Effects coding is an alternative to dummy coding using the values of -1 and +1 to represent two categories of responses. Effects coding uses the values of -0.5 and +0.5 to represent two categories of responses, thereby avoiding the interpretative difficulties associated with dummy coding. Reverse coding involves reversing the scores of negatively worded items to compute a composite score, while inverse coding is not a statistical technique. Verified coding is not a term used in statistical analysis.
