In a continuous series, the mode is determined by two methods, as given below
(i) Inspection Method If the items are concentrated in one class, we determine the modal class and then to determine the exact value, we apply the formula

$M_{ 0 }$ = $l_{ 1 }$ + $f_{ 1 }$ - $f_{ 0 }$ / 2 $f_{ 1 }$ - $f_{ 0 }$ - $f_{ 2 }$ X h

(ii) Grouping Method If values are concentrated at more than one value, then a grouping table and an analysis table is prepared in the same way as in discrete series and then to know the exact value of the mode, we apply the formula given above.
