Question

The following data shows monthly savings of 100 families . Calculate the mode of the given frequency distribution.

\begin{matrix} M o n t h l y s a v i n g s (R s) & N u m b e r o f f a m i l i e s 1000 - 2000 & 14 2000 - 3000 & 15 3000 - 4000 & 21 4000 - 5000 & 27 5000 - 6000 & 25 \end{matrix}

Options:

A . 4790

B . 4760

C . 4750

D . 4780

Answer: Option C
:
C
Modal class is 4000-5000 within

f_{1}

= 27,

f_{0}

= 21,

f_{2}

= 25, I = 4000, h = 1000
Mode = l +

\frac{f_{1} - f_{0}}{2 f_{1} - f_{0} - f_{2}} \times h

Mode = 4000 +

\frac{6}{8}

\times

1000
= 4750
