_D_e_s_c_r_i_p_t_i_o_n:

     Data from a completely randomized design where four different
     methods of growing corn resulted in various yields per acre on
     various plots of ground where the  four methods were tried.
     Ordinarily, only one statistical analysis is used,  but here we
     will use the kuskal-wallis test so that a rough comparison may be
     made with the mediasn test.

_U_s_a_g_e:

     data(corn)

_F_o_r_m_a_t:

     A data frame with 34 observations on the following 3 variables.

     '_m_e_t_h_o_d' a numeric vector

     '_o_b_s_e_r_v_a_t_i_o_n' a numeric vector

     '_r_x' a numeric vector

_D_e_t_a_i_l_s:

     The observations are ranked from the smallest, 77, of rank 1 to
     the largest 101,  of rank N=34. Ties values receive the averarge
     rank.
