Find the mode of the given frequency distribution:
Find the mode of the given frequency distribution :
| Class | Frequency |
| $\displaystyle 15$-$\displaystyle 25$ | $\displaystyle 6$ |
| $\displaystyle 25$-$\displaystyle 35$ | $\displaystyle 11$ |
| $\displaystyle 35$-$\displaystyle 45$ | $\displaystyle 22$ |
| $\displaystyle 45$-$\displaystyle 55$ | $\displaystyle 23$ |
| $\displaystyle 55$-$\displaystyle 65$ | $\displaystyle 14$ |
| $\displaystyle 65$-$\displaystyle 75$ | $\displaystyle 5$ |
Marking-scheme solution
Modal class is $\displaystyle 45$-$\displaystyle 55$
\[\begin{array}{l}
\text { Mode }=45+10 \times \frac{23-22}{46-22-14} \\
=46
\end{array}
\]
