Time series analysis is a statistical methodology appropriate for longitudinal research designs and the data obtained is also known as longitudinal data. The data is identified and treated as a stretch/series of values and time being treated as the parameter . One of the advantages this form of analysis is it gives the researcher freedom to investigate the pattern of intervention (B) effects across time. Velicer, 2003, has identified five pointers to be followed when such a longitudinal framework is applied, a) effects of intervention temporary or permanent ?; b) does the intervention casue changes in any specific behaviors or on all of them ; c) is the intervention able to induce or enhance a causal effect change present in the underlying behavior process; d) is the intervention capable to bring variance ; e) is the intervention able to cause a change in the nature of the dependency during the period of assessment “time”.
