An analysis of the fonvard-backward asymmetry in $Z^0$ decays using data from the Collider Detector at Fermilab provides a measurement of $$sin^2 \bar{\theta}B_w$$. The forward-backward asymmetry is measured to be (5.2 ± 5.9 (stat)± 0.4 (sys))%, which implies $$sin^2 \bar{\theta}_w$$ = 0.228 $$^{+0.017}_{-0.015}$$(stat)± 0.002 (sys), after QCD, QED, and weak corrections. vVhen higher order weak corrections are included, the measured value of $$sin^2 \theta_w$$ is consistent with previous measurements over a broad range of top quark masses
