numbers on the left-hand side and the various probable values of mode on the right-hand side. The
values against which frequencies are the highest and marked in the grouping table are then entered
by means of a bar in the relevant ‘box’ corresponding to the values they represent.
The procedure of preparing grouping table and analysis table shall be clear from the following
example:
