This paper highlights Hybrid Coding Method (HCM) for Planned Comparison of Treatment. Coding in regression analysis has been widely used with varying applications. Various coding structures have been developed in the past. Coding structures such as Dummy, Simple, Hermert, Reverse Hermert, Forward Differencing and Backward Differencing were developed to deal with specified (simple) hypotheses. A mixture of Dummy, Simple and Contrast coding was considered. We derived the expression for the mix of dummy and simple coding to form the Hybrid coding. The empirical results showed that the hybrid method can be used to test some specific hypotheses which are generally complex in nature.
