## Mean, median and mode for grouped data

Let $x_1, x_2, \cdots , x_n$ have frequencies $f_1, f_2, \cdots ,f_n$ respectively, then the Harmonic Mean is given by

$$\begin{equation*} Mean =\overline{X} = \frac{1}{N}\sum_{i=1}^{n}f_ix_i\quad \mbox{ where }N = \sum_{i=1}^{n} f_i \end{equation*}$$

In case of continuous frequency distribution, $x_i$'s are the mid-values of the respective classes.
