  We calculate the critical coupling $4/g_c^2$ and critical exponent $\beta$
for the order parameter in SU(2) lattice gauge theory by applying of the finite
size scaling technique and the method proposed by Kouvel and Fisher for
analysis of experimental data. In contrast to the standard finite size scaling
approach, this method allows to determine simultaneously both $g_c^2/4$ and
$\beta$ as two parameters of the linear fit to the Monte-Carlo data.
