The top quark is most often produced in t$$\bar{t}$$ pairs via the strong interaction, however, electroweak production of a single top quark is also possible. Electroweak or 'single-top' quark production is more difficult to observe than t$$\bar{t}$$ production. A measurement of single-top quark production can provide an interesting test of the Standard Model as well as a measurement of the CKM matrix element V_tb. This thesis describes a measurement of single-top quark production in pp collisions at √s=1.96 TeV usign the CDF II detector at the Fermilab Tevatron. This search is performed using a Multivariate Likelihood technique with 2.2 fb^-1 of data.
