(D) In the formula for calculating the mode of grouped data,the variables are defined as follows:$Z$ is the mode.$l$ is the lower limit of the modal class.$f_{1}$ is the frequency of the modal class.$f_{0}$ is the frequency of the class preceding the modal class.$f_{2}$ is the frequency of the class succeeding the modal class.$c$ is the size of the class interval.Therefore,$f_{2}$ represents the frequency of the class succeeding the modal class.

In the formula $Z = l + \left( \frac{f_{1} - f_{0}}{2f_{1} - f_{0} - f_{2}} \right) \times c$ for the mode,$f_{2} = \ldots \ldots \ldots$

A
frequency of the modal class
B
