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

     The classical data of Michaelson and Morley on the
     speed of light.  The data consists of five experiments,
     each consisting of 20 consecutive "runs".  The response
     is the speed of light measurement, suitably coded.

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

     The data is here viewed as a randomized block experi-
     ment with "experiment" and "run" as the factors.  "run"
     may also be considered a quantitative variate to
     account for linear (or polynomial) changes in the mea-
     surement over the course of a single experiment.

_V_a_l_u_e_:

     The data frame contains the following components:

    Expt: The experiment number, from 1 to 5

     Run: The run number within each experiment

   Speed: Speed-of-light measurement

_C_A_T_E_G_O_R_Y_:

     Analysis of Variance.
